HP E1366A & E1367A RF Multiplexer Module User’s Manual
Chapter 1 Getting Started with the HP E1366A/E1367A RF Multiplexers Using This Chapter This chapter includes an RF multiplexer’s description, addressing guidelines, and an example to check initial operation. Chapter contents are: • Multiplexer Module Description . . . . . . . . . . . . . . . . . . . . . Page 11 • Programming the Multiplexer Module . . . . . . . . . . . . . . . . .

Figure 1-1.
Typical Configuration The multiplexer relays are configured in a “ tree” structure which provides high isolation and low VSWR (voltage standing wave ratio). Each channel can switch user inputs up to 42 Vdc or 42 Vac peak. User input frequencies to the multiplexers can be from dc to 1.3 GHz. The multiplexers can be configured for several arrangements, such as standard, tree, or matrix. You can use single scanning, multiple scanning, or continuous scanning for any configuration.
Multiplexer Card Numbers The multiplexer card number depends on the switchbox configuration (single-module or multiple-module) set for the multiplexers. (Leading zeroes can be ignored for the card number.) For a single-module switchbox, the card number is always 01. For a multiple-module switchbox, the card numbers are 01, 02,...,n. The switch module with the lowest logical address is always card number 01. The card number with the next successive logical address is card number 02, and so on.
Use commas (,) to form a channel list or use a colon (:) to form a channel range. Only valid channels can be accessed in a channel list or channel range. Also, the channel list or channel range must be from a lower channel number to a higher channel number. For example, SCAN (@100:213) is acceptable, but SCAN (@213:100) generates an error.

Chapter 2 Configuring the HP E1366A/E1367A RF Multiplexers Using This Chapter This chapter shows how to make user connections to the RF multiplexers and how to configure the multiplexer modules. Chapter contents are: • • • • Warnings and Cautions . . . . . . . . . . . . . . . . . . . . . . . . . . . . . Connecting User Inputs . . . . . . . . . . . . . . . . . . . . . . . . . . . . . Typical Multiplexer Configurations . . . . . . . . . . . . . . . . . . . Changing Multiplexer Components. . . . . . . . . .
Caution CENTER CONDUCTOR MAY SHORT TO SHIELD. Each channel’s center conductor may momentarily short to the shield when the channel is opened or closed. Use only resistive (50Ω or 75Ω) or current-limited (<1 A) inputs with less than 0.1 µF total capacitance. Caution STATIC-SENSITIVE DEVICE. Use anti-static procedures when removing, configuring, and installing a module. The multiplexer modules are susceptible to static discharges. Do not install a multiplexer without its metal shield attached.
Some guidelines for user input cabling are: • For best high-frequency performance, user cabling should have at least two braided shields or one braid and a foil wrap. • Always use shielded coaxial cables with the characteristic impedance of the multiplexer used (50Ω or 75Ω). Keep cables as short as possible, especially in high-frequency circuits or pulse circuits where a rise/fall time of <50 nsec is critical. • Long cables can add delay time which can cause timing problems.
Typical Multiplexer Configurations Typical RF multiplexer configurations are: • Standard configuration (2 x 4:1 multiplexer) • Tree configuration (1 x 12:1 multiplexer) • Matrix-type configuration (4:1 to 4:1 multiplexer) Standard Configuration Figure 2-2 shows the standard configuration (2 x 4:1) for the RF multiplexers. With this configuration, you can switch channels 00-03 to com 00 and switch channels 10-13 to com 10. One channel per bank can be connected to its common at a time. Figure 2-2.
Tree Configuration Figure 2-3 shows a typical tree configuration which uses two RF multiplexers to provide a 1 x 12:1 multiplexer. This configuration provides isolation of test points while maintaining characteristic impedance. With tree configuration, signal delay time is more than doubled since the signal must pass through two channel banks plus extra cabling. Keep cables as short as possible, especially between channel banks, to minimize delay. Figure 2-3.
Matrix-Type Configuration Figure 2-4 shows the two banks of an RF multiplexer connected to form a matrix-type arrangement. This configuration provides a way to connect multiple devices under test (DUTs) to multiple test instruments. With this configuration, only one channel in bank 0 (one “ row” ) can be connected to one channel in bank 1 (one “ column” ) at a time. Figure 2-4.
Changing Multiplexer Components As required, you can change the logical address switch setting, replace the protection fuses, change the interrupt priority jumper setting, or remove channel termination resistors. See Figure 2-5 for locations. Figure 2-5.

Chapter 3 Using the HP E1366A/E1367A RF Multiplexer Module Using This Chapter This chapter provides examples to switch multiplexer channels and to scan multiplexer channels. As required see Chapter 4, Understanding the RF Multiplexers, to modify the examples for your application. Also, see Chapter 5, RF Multiplexers Command Reference, for command information. Chapter contents are: • Multiplexer Commands . . . . . . . . . . . . . . . . . . . . . . . . . . . . . Page 25 • Switching Channels . . . . . . . .
Example: Standard Switching This example connects channel 02 to com 00 of an RF multiplexer in standard configuration. The multiplexer is defined as a single-multiplexer switchbox instrument. See the following figure for typical user connections. To connect channel 02 to com 00, execute: CLOS (@102) ! Connect channel 02 to com 00. 1 is the card number and 02 is the channel number. To open the channel, use OPEN (@102). Figure 3-1.
Example: Tree Switching This example uses two RF multiplexers in a tree configuration to connect com 10 of multiplexer #1 with channel 12 of multiplexer #2. The two multiplexers form a multiple-multiplexer switchbox instrument with multiplexer #1 as card 01 and multiplexer #2 as card 02. See the following figure for typical user connections. To make this connection, execute: CLOS (@112,212) ! Connect com 10 of multiplexer #1 to channel 12 of multiplexer #2. To open the channels, use OPEN (@112,212).
Example: Matrix-Type Switching This example connects channel 13 to channel 01 of an RF multiplexer in matrix-type configuration. The multiplexer is defined as a single-module switchbox instrument. See the following figure for typical user connections. To connect channel 13 to channel 01, execute: CLOS (@101,113) ! Connect channel 01 to channel 13. 1 is the card number and 01, 13 are channel numbers. Figure 3-3. Matrix-Type Switching To open the channels, use OPEN (@101,113).
Scanning Channels • Scanning channels consists of closing a set of channels, one channel at a time. You can scan any combination of channels for a single-multiplexer or multiple-multiplexer switchbox. • Single, multiple, or continuous scanning modes are available. Any switching configuration can be used for scanning. See Chapter 4. Example: Scanning Using Trig Out Port This example shows one way to synchronize instrument measurements of DUTs with RF multiplexer channel closures.
Scanning Channels Comments Scan List Can Extend Across Boundaries. For multiple-multiplexer switchbox instruments, the scan list can extend across multiplexer boundaries. For example, for a two-multiplexer switchbox instrument, SCAN (@100:213) will scan all channels in both multiplexers. Setting Multiple/Continuous Scans. Use ARM:COUN to set from 1 to 32767 scans through the scan list. Use INIT:CONT ON to set continuous scanning. See Chapter 4.
Chapter 4 Understanding the HP E1366A/E1367A RF Multiplexers Using This Chapter This chapter explains techniques to scan RF multiplexer channels and shows how to use the Scan Complete bit. The chapter contents are: • • • • Scanning Channels Commands . . . . . . . . . . . . . . . . . . . . . . Using Scanning Trigger Sources . . . . . . . . . . . . . . . . . . . . . Scanning with External Instruments. . . . . . . . . . . . . . . . . . . Using the Scan Complete Bit . . . . . . . . . . . . . . . . . . . . .
Sets Number of Scanning Cycles ARM:COUN sets 1 to 32767 scans through the channel list per INIT command. Default is one scanning cycle. Selects the Trigger Source TRIG:SOUR defines the trigger source to advance the scan. Default is TRIG:SOUR IMM. TRIG:SOUR? queries the current trigger source.
Trigger Hold (TRIG:SOUR HOLD) Immediate Triggering (TRIG:SOUR IMM) TRIG:SOUR HOLD prevents execution of triggers until trigger source is changed. Can use TRIG command to trigger a switchbox set to TRIG:SOUR HOLD. TRIG:SOUR IMM sets immediate (internal) triggering. The scan list is automatically advanced. This is the default trigger mode. Advance Scan (TRIG) Can use TRIG command to advance the scan list when switchbox is in TRIG:SOUR HOLD or TRIG:SOUR BUS.
Example: Scanning with External Device This example uses the HP E1300A/E1301A mainframe "Trig Out" port to synchronize the RF multiplexer channel closures to an external measurement device. See the figure below for typical user connections. For measurement synchronization, the HP E1300A/E1301A Trig Out BNC port is connected to the instrument External Trigger In port.
Example: Scanning Using "Trig Out" and " Event In" Ports This example uses the HP E1300A/E1301A mainframe "Trig Out" and "Event In" ports to synchronize RF multiplexer channel closures with an external measurement device. See the figure below for typical user connections. For this example, the mainframe and instrument are connected via HP-IB with mainframe address of 709 and instrument address of 722. The RF multiplexer’s logical address is 120 (secondary address =120/8 =15).
Using the Scan Complete Bit You can use the Scan Complete Bit (bit 8) in the Operation Status register of a switchbox to determine when a scanning cycle completes (no other bits in the register apply to the switchbox). Bit 8 has a decimal value of 256 and you can read it directly with the STAT:OPER? command. Refer to STATus:OPERation[:EVENt]? command in Chapter 5 for an example. When enabled by the STAT:OPER:ENAB 256 command, the Scan Complete Bit will be reported as bit 7 of the Status register.
l Chapter 5 HP E1366A/E1367A RF Multiplexers Command Reference Using This Chapter This chapter describes Standard Commands for Programmable Instruments (SCPI) and summarizes IEEE 488.2 Common (*) commands applicable to both RF Multiplexer modules. See the appropriate HP B-size or C-size configuration guide for additional information on SCPI and Common commands. This chapter contains the following sections. • • • • Command Types . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
Command Separator A colon (:) always separates one command from the next lower-level command as shown below: ROUTe:SCAN:MODE? Colons separate the root command from the second-level command ([ROUTe:]SCAN) and the second level from the third level (SCAN:MODE?). Abbreviated Commands The command syntax shows most commands as a mixture of upper- and lowercase letters. The uppercase letters indicate the abbreviated spelling for the command. For shorter program lines, send the abbreviated form.
Parameters Parameter Types. The following table contains explanations and examples of parameter types you might see later in this chapter. Table 5-1. SCPI Parameter Types Parameter Type Explanations and Examples Numeric Accepts all commonly used decimal representations of numbers including optional signs, decimal points, and scientific notation. 123, 123E2, -123, -1.23E2, .123, 1.23E-2, 1.23000E-01. Special cases include MIN, MAX, and INF.
SCPI Command Reference This section describes the Standard Commands for Programmable Instruments (SCPI) commands for the RF multiplexers. Commands are listed alphabetically by subsystem and within each subsystem. ABORt The ABORt subsystem stops a scan in progress when the scan is enabled via the interface, and the trigger modes are TRIGger:SOURce BUS or TRIGger:SOURce HOLD.
ARM The ARM subsystem selects the number of scanning cycles (1 through 32767) for each INITiate command. Subsystem Syntax :COUNt ARM :COUNt MIN | MAX :COUNt? [MIN | MAX] ARM:COUNt MIN | MAX allows scanning cycles to occur a multiple of times (1 to 32767) with one INITiate command when INITiate:CONTinuous OFF |0 is set. MIN sets 1 cycle and MAX sets 32767 cycles.
:COUNt? ARM:COUNt? [MIN | MAX] returns current number of scanning cycles set by ARM:COUNt. The current number of scan cycles is returned when MIN or MAX is not supplied. With MIN or MAX passed as parameters, MIN returns 1 and MAX returns 32767.
DISPlay The DISPlay subsystem monitors the channel state of a selected module (or card) in a switchbox. This subsystem operates only with mainframes which have a display, such as the HP 75000 Series B Mainframe (HP E1301A). Subsystem Syntax :MONitor[:STATe] DISPlay :MONitor [:STATe] :CARD | AUTO DISPlay:MONitor[:STATe] turns the monitor mode on or off.
:MONitor:CARD DISPlay:MONitor:CARD | AUTO selects the module in a switchbox to be monitored. Parameters Comments Parameter Name Parameter Type Range of Values | AUTO numeric 1-99 • Selecting a Specific Module to be Monitored: Use the DISPlay:MONitor:CARD command to send the module number for the switchbox to be monitored. • Selecting the Present Module to be Monitored: Use the DISPlay:MONitor:AUTO command to select the last module addressed by a switching command (e.g.
INITiate The INITiate subsystem selects continuous scanning cycles and starts the scanning cycle. Subsystem Syntax :CONTinuous INITiate :CONTinuous ON | OFF | 1 | 0 :CONTinuous? [:IMMediate] INITiate:CONTinuous ON | OFF | 1 | 0 enables or disables continuous scanning cycles for the switchbox.
:CONTinuous? Example INITiate:CONTinuous? queries the scanning state. With continuous scanning enabled, the command returns 1. With continuous scanning disabled, the command returns 0. Query Continuous Scanning State This example enables continuous scanning of a switchbox and queries the state. Since continuous scanning is enabled, INIT:CONT? returns 1.
OUTPut The OUTPut subsystem enables or disables the “ Trig Out” port of the HP E1300A/E1301A mainframe or the HP E1405A/E1406A module. Subsystem Syntax [:STATe] OUTPut [:STATe] ON | OFF | 1 | 0 [:STATe]? OUTPut[:STATe] ON | OFF | 1 | 0 enables/disables the “ Trig Out” port on the rear panel of the HP E1300A/E1301A mainframe or the HP E1405A/E1406A module. OUTPut[:STATe] ON | 1 enables the port and OUTPut[:STATe] OFF | 0 disables the port.
[ROUTe:] The ROUTe subsystem controls switching and scanning operations for RF multiplexer modules in a switchbox. Subsystem Syntax CLOSe [ROUTe:] CLOSe CLOSe? OPEN OPEN? SCAN :MODE NONE | VOLT | RES | FRES :MODE? [ROUTe:]CLOSe closes the RF multiplexer channels specified by channel_list. The channel_list has the form (@ccnn) where cc = card number (01-99) and nn = channel number (00-03 and 10-13).
CLOSe? Comments [ROUTe:]CLOSe? returns the current state of the channel(s) queried. The channel_list is in the form (@ccnn) (see [ROUTe:]CLOSe for definition). The command returns 1 for channel(s) closed or returns 0 for channel(s) opened. • Query is Software Readback: The [ROUTe:]CLOSe? command returns the current software state of the channel(s) specified. It does not account for relay hardware failures. A maximum of 127 channels at a time can be queried for a multi-module switchbox.
OPEN? [ROUTe:]OPEN? returns the current state of the channel(s) queried. The channel_list is in the form (@ccnn) (see [ROUTe:]OPEN for definition). The command returns 1 for channel(s) open or returns 0 for channel(s) closed. Comments • Query is Software Readback: The [ROUTe:]OPEN? command returns the current software state of the channels specified. It does not account for relay hardware failures. A maximum of 127 channels at a time can be queried for a multi-module switchbox.
SCAN [ROUTe:]SCAN defines the channels to be scanned. The channel_list has the form (@ccnn) where cc = card number (01-99) and nn = channel number (00-03 and 10-13). Parameters Comments Parameter Name Parameter Type Range of Values numeric cc00-cc03, cc10-cc13 • Defining Scan List: When executing [ROUTe:]SCAN, the channel list is checked for valid card and channel numbers. An error is generated for an invalid channel list.
SCAN:MODE [ROUTe:]SCAN:MODE NONE | VOLT | RES | FRES sets the scan mode for the RF multiplexers. NONE, VOLT, and RES have no effect on multiplexer operation. With FRES, the switch is set for “paired-channel” scanning. That is, when a channel in bank 0 is closed, the associated channel in bank 1 is simultaneously closed.
STATus The STATus subsystem reports the bit values of a Standard Operation Status register. It enables the Status register to set a bit after a bit is set to 1 by the Standard Operation register. Subsystem Syntax :OPERation[:EVENt]? Comments STATus :OPERation [:EVENt]? :ENABle STATus:OPERation[:EVENt]? returns the bit value of the Operation Status register (only bit 8 is used by the multiplexer modules).
SYSTem The SYSTem subsystem returns error numbers/messages in the error queue of a switchbox, and returns module types and descriptions in a switchbox. Subsystem Syntax :ERRor? SYSTem :ERRor? :CDEScription? :CTYPe? < number > :CPON < number > | ALL SYSTem:ERRor? returns the error numbers/messages in the error queue of a switchbox. See Appendix C for error message information.
Parameters Comments Parameter Name Parameter Type Range of Values numeric 1-99 • RF Multiplexers Model Number: The SYSTem:CTYPe? command returns "HEWLETT-PACKARD,E1366A,0,A.01.00" (E1366A), or returns "HEWLETT-PACKARD,E1367A,0,A.01.00" (E1367A), where the "0" after "E1366A" or "E1367A" is the module serial number (always 0) and "A.01.00" is an example of the module revision code number.
TRIGger The TRIGger subsystem controls the triggering operation of RF multiplexer modules in a switchbox. Subsystem Syntax TRIGger [:IMMediate] :SOURce BUS | EXTernal | HOLD | IMMediate :SOURce? [:IMMediate] TRIGger[:IMMediate] causes a trigger to occur when the defined trigger source is TRIGger:SOURce HOLD or TRIGger:SOURce BUS.
:SOURce TRIGger:SOURce BUS | EXTernal | HOLD | IMMediate specifies the trigger source to advance the channel list during scanning. Parameters Comments Parameter Name Parameter Type Range of Values BUS discrete *TRG or GET command EXTernal discrete “Event In” BNC port HOLD discrete Hold triggering IMMediate discrete Immediate triggering • Enabling the Trigger Source: The TRIGger:SOURce command only selects the trigger source. The INITiate[:IMMediate] command enables the trigger source.
Example Scanning Using External Triggers This example uses external triggering (TRIG:SOUR EXT) to scan channels 00 through 03 of a single-module switchbox. The trigger source to advance the scan is the input to the “ Event In” BNC on an HP E1300A/E1301A mainframe. When INIT is executed, the scan is started and channel 00 is closed. Then each trigger received at the “ Event In” BNC advances the scan to the next channel.
IEEE 488.2 Common Commands The following table lists the IEEE 488.2 Common (*) Commands that apply to the RF Multiplexer module. The operation of some of these commands is described in Chapter 4 of this manual. For information on Common Commands, refer to the HP B-size configuration guide or the ANSI/IEEE Standard 488.2-1987. Command Title Description *IDN? *RST Identification Reset Returns identification string of the switchbox.
Command Quick Reference The following tables summarize SCPI and IEEE 488.2 Common (*) commands for the RF Multiplexer modules used in a switchbox. SCPI Commands Quick Reference Command Description ABORt Abort a scan in progress. ARM :COUNt :COUNt? [MIN |MAX] Multiple scans per INIT command. Query number of scans.

Relay Life Electromechanical relays are subject to normal wear-out. Relay life depends on several factors. The effects of loading and switching frequency are briefly discussed below: Relay Load. In general, higher power switching reduces relay life. In addition, capacitive/inductive loads and high inrush currents (e.g., turning on a lamp or starting a motor) reduces relay life. Exceeding specified maximum inputs can cause catastrophic failure. Switching Frequency. Relay contacts heat up when switched.

Appendix B HP E1366A/E1367A Multiplexer Registers Register Definitions The HP E1366A and HP E1367A RF multiplexers are register-based slave devices.
Addressing the Registers To read or write to specific registers, you must use the register address. Since the addresses for HP 75000 Series B or Series C plug-in modules are A00 through A15, use the VME A16 mnemonic for the address space. The address space within the mainframe/command module memory map depends on the mainframe/command module used. For example, the address of the HP E1300A/E1301A Mainframe starts at 1F0000h.
Writing to the Registers You can write to the following RF multiplexer registers: • Status/Control register (base + 04h) • Bank 0 Channel Enable register (base + 08h) • Bank 1 Channel Enable register (base + Ah) Status/Control Register The only write allowed to the Status/Control register (base + 04h) is to bit 0. Writing a “ 1” to bit 0 resets the multiplexer to its power-on state with all channels open and terminated and both commons open.
