Only service trained personnel should make repairs to the Agilent 3499A/B/C mainframes and/or the plug-in modules. WARNING Make sure to disconnect all the wiring from the Agilent 3499A/B/C plug-in modules to the external devices in order to execute the Verification Tests.
Table 4-1. Error Number Correction Description +3 RS-232 test failed. +4 Front-panel test failed. If, during the display test, a segment or segments malfunctioned, a problem exists on the Controller board or the Display assembly. Refer to “Agilent 3499A/B/C Problem Isolation” on Page 80 for problem isolation information. If the front-panel test failed, a problem exists on the front panel circuitry; if any of the other internal tests failed, the Controller board is malfunctioned.
If “RS232 TEST” is displayed on the front panel of the Agilent 3499A/B/C, the RS-232 test passed. Otherwise, the RS-232 test failed. Keyboard Test All the keys on the front panel of an Agilent 3499A/B/C can be tested easily by pressing the keys. If one or more keys has no response, a problem exists in either the Keyboard Assembly, or the Controller board. Refer to “Agilent 3499A/B/C Problem Isolation” on Page 80 for problem isolation information.

Write a binary 10101010 to any one of the 8-bit ports (in order to open every other line) and verify the data has been transferred to all the other ports. Take an Agilent N2263A for example, if a data (10101010) has been written to the port s02, this data should be transferred to other ports s00, s01 and s03.
Correction Replace the DIO module with a new one if it is failed. Agilent 44472A Verification Tests The VHF Switch module consists of two 4-to-1 MUXs with BNC connections. Only the center conductor of each channel is switched. The outer conductors (shield) of all channels in a particular MUX are connected together and unswitched. Tests Procedure To test a channel: 1. Remove any external wiring from the rear of the 44472A. Reset the 44472A and press Mon; 2.
Coaxial Switches; these coaxial switches come in 3/4/5-port configurations. To verify that the 33311B Coaxial Switches on the Agilent 44476A (or the switches you provide on the Agilent 44476B) are functioning, verify continuity between the common port and the port connected to it. Also, verify there is no continuity between the common port and any unconnected ports.
4. Repeat Steps 2 & 3 to verify the other channels; 5. Close all the channels on the Agilent 4476A/B; 6. Verify continuity between the Channel 00 center conductor of the common port and center conductor of port 2. For an Agilent 44476B, you must determine which ports should have continuity for Channel 00 and verify it; 7. Verify there is no continuity between the common port and port 1 of channel 00. For the Agilent 44476B, you must determine which ports should not have continuity and verify they do not; 8.

Agilent 44477A Test Fixture To Verify the NO Contacts: 1. Connect a Multimeter between TP1 (C) & TP2 (NO), reset the Agilent 44477A. The Multimeter should show an open circuit; 2. Close Channel 00 and check the Multimeter for an indication of closure.
Agilent 44478A/B Verification Tests Agilent 44478A/B consists of two 4-to-1 MUXs (Group 00 & Group 10) that can switch signals bidirectionally. Each group has a separate ground for isolation between groups and this ground is unswitched (Figure 4-7). To verify that the relays in each group are functioning, verify continuity between the center conductor of the common BNC and each channel’s BNC center conductor when that channel is closed.
Tests Procedure To verify that the relays in each group are functioning: 1. 2. 3. 4. 5. 6. 7. 8. 9. Correction Remove any external wiring from the Agilent 44478A/B connectors; Reset the Agilent 44478A/B and press Mon; Create a scan list including all the channels on an Agilent 44478A/B; Connect the Multimeter between the center conductor of the COM 00 connector and the center conductor of the channel under test (start with CH 00).
Agilent N2280A/81A/82A Verification Tests Agilent N2280A consists of four 1-to-2 Optical Switches, each 1-to-2 Optical Switch should be tested independently. Agilent N2281A consists of two 1-to-4 Optical Switches, each 1-to-4 Optical Switch should be tested independently. Agilent N2282A consists of one 1-to-8 Optical Switch.
Test Procedure Before testing the Agilent N2280A/81A/82A Optical Switch Module, the user should have an Optical Multimeter in hand. When testing, the two Optical probes of the Optical Multimeter should be connected to the two end-connectors of one channel of the specific Optical Switch, then execute closing and opening commands on it , you can find whether this channel is normal or not via the optical multimeter’s display. To verify that the optical switches in each group are functioning: 1.

Chapter 5 Service Introduction This Chapter provides general service related information about the Agilent 3499A/B/C Switch/Control System. This includes safety considerations, static-handling procedures, and problem isolation processes.

Any assembly or subassembly removed from the mainframe MUST be handled in accordance with anti-static handing procedures. The following guidelines are the minimum requirements for a static safe service environment. • The work bench should be equipped with a conductive table mat. The mat should be grounded to earth ground through a 1 MΩ resistor. The mat should be equipped with at least one swivel connected to the swivel connector for connecting wrist straps.
the problem is mostly on the mainframe; if the problem is solved, the problem may be caused by one or more plug-in module. Plug-in Module Substitution The easiest and fastest method to isolate a failure to a particular assembly is the board substitution technique. The technique calls for the suspected bad board to be replaced with a known good board. If the problem is solved, the replaced board or assembly had the problem. A limited substitution may be performed to isolate a faulty plug-in module.

Appendix B Error Messages Agilent 3499A/B/C Switch/Control System can be operated in either SCPI mode or 3488A mode. The error messages are different in different system modes. This Appendix lists all these error messages. In SCPI Mode • Errors are retrieved in first-in-first-out (FIFO) order. The first error returned is the first error that was stored. Errors are cleared as you read them. When you have read all errors from the queue, the ERROR annunciator turns off and the errors are cleared.
Execution Errors -101 Invalid character An invalid character was found in the command string. You may have used an invalid character such as #, {, $, or % in the command header or within a parameter. Example: OPEN {@101) -102 Syntax error Invalid syntax was found in the command string. You may have inserted a blank space before or after a colon in the command header, or before a comma. Or you may have omitted the ‘‘@’’ character in the channel list syntax.
124 -131 Invalid suffix A suffix was incorrectly specified for a numeric parameter. You may have misspelled the suffix. -134 Suffix too long A header suffix is the number that can be appended to the end of some command headers. This error is generated if the header suffix contains more than 12 characters. -138 Suffix not allowed A suffix was received following a numeric parameter. You may have misspelled the suffix.

The errors are also cleared when you read the queue. -410 Query INTERRUPTED A command was received which sends data to the output buffer, but the output buffer contained data from a previous command (the previous data is not overwritten). The output buffer is cleared when power has been off or after a bus Device Clear. -420 Query UNTERMINATED The instrument was addressed to talk (i.e.
112 Not able to perform requested operation The requested operation is not valid for the instrument. Example: FUNC 3,BIWIRE2 (the module in Slot 3 is not an Agilent N2260A). 113 Block name not exist In an Agilent 3499A/B/C, maximum two blocks can be defined. The two defined blocks can be read and written, etc. If you read or write a block that has not been previously defined, this error occurs.
Note A string “+0” read back (with command *TST) indicates that all the tests have passed. In this case, a string “PASSED” displays on the front panel of the instrument.
In 3488A Mode Error Conditions In 3488A mode, you can also query the error queue when the ERROR annuciator is on. The returned decimal value is equal to the sum of the values of the possible error conditions, as defined in Table 6-20. Table 6-20. Error Conditions in 3488A Mode Weighted Value Note Error Condition 1 Syntax Error 2 Execution Error which include: a. Parameter out of range; b. Module type mismatch; c.
