1 General Information Introduction This manual contains information required to test, troubleshoot, and repair the Agilent E1330A/B Quad 8-Bit Digital I/O Module. See the Agilent E1330A/B User’s Manual for additional information on the Agilent E1330A/B. Figure 1-1 shows the Agilent E1330A/B Quad 8-Bit Digital I/O Module. Figure 1-1.
Safety Considerations This product is a Safety Class I instrument that is provided with a protective earth terminal when installed in the mainframe. Check the mainframe, Digital I/O Module, and all related documentation for safety markings and instructions before operation or service. Refer to the WARNINGS page (page iii) in this manual for a summary of safety information. Safety information for preventive maintenance, testing, and service follows and is also found throughout this manual.
WARNING USING AUTOTRANSFORMERS. If the mainframe is to be energized via an autotransformer (for voltage reduction) make sure the common terminal is connected to neutral (that is, the grounded side of the main’s supply). CAPACITOR VOLTAGES. Capacitors inside the mainframe may remain charged even when the mainframe has been disconnected from its source of supply. USE PROPER FUSES.
Digital I/O Description NOTE Agilent E1330A/B Description The Agilent E1330A/B Digital I/O Module is an "instrument" in a VXIbus mainframe. As such, each Digital I/O module is assigned an error queue, input and output buffers, and a status register. Instruments are based on the logical addresses of the plug-in modules. See the Agilent 75000 Series B Installation and Getting Started Guide to set the addresses to create an instrument.
Digital I/O Module Serial Numbers Digital I/O modules covered by this manual are identified by a serial number prefix listed on the title page. Agilent Technologies uses a two-part serial number in the form XXXXAYYYYY, where XXXX is the serial prefix, A is the country of origin (A=USA), and YYYYY is the serial suffix. The serial number prefix identifies a series of identical instruments. The serial number suffix is assigned sequentially to each instrument.
Recommended Test Equipment Table 1-1 lists the test equipment recommended for testing, adjusting, and servicing the Digital I/O modules. Essential requirements for each piece of test equipment are described in the Requirements column. Table 1-1. Recommended Test Equipment Instrument Requirements Recommended Model Use* Controller, GPIB GPIB compatibility as defined by IEEE Standard 488-1987 and the identical ANSI Standard MC1.1: SH1, AH1, T2, TE0, L2, LE0, SR0, RL0, PP0, DC0, DT0, and C1, 2, 3, 4, 5.

2 Verification Tests Introduction This chapter describes the verification tests for the Agilent E1330A/B modules. The three levels of test procedures described in this chapter are used to verify that the Agilent E1330A/B: • is functional (Functional Verification Test) • meets selected testable specifications (Operation Verification) • meets all testable specifications (Performance Verification) Test Conditions/ Procedures See Table 1-1 for test equipment requirements.
Functional Verification Test Procedure The Functional Verification Test for the Agilent E1330A/B modules consists of sending the *IDN? command and checking the response. This test can be used to verify that the module is connected properly and is responding to a basic command. 1. Verify that the module is properly installed in mainframe 2. Verify that the mainframe has passed its power-on test. 3. Send *IDN? to the module (see example following) 4.
Performance Verification Tests The procedure in this section is used to test the module’s electrical performance using the specifications in Appendix A — Specifications of the Agilent E1330A/B Modules User’s Manual as the performance standard. The Performance Verification test is a test of each Digital I/O line on each port and a test of the three main handshake lines for each port. This test is sufficient to determine that the module is operating within specifications.

3. Repeat for Ports 1 through 3 • Repeat step 2 for ports 1, 2, and 3. • Use SOUR:DIG:DATAn #Bssssssss and MEAS:DIG:DATAn? where n = port number and ssssssss = the binary string. • For Port 1 Write, use Port 3 Read. For Port 2 Write, use Port 0 Read. For Port 3 Write, use Port 1 Read. 4. Check Port 0 CTL and Port 2 FLG handshake lines • • • • • • • • • Send *RST to the module. Send SOUR:DIG:CONT0 1 to the module. Send MEAS:DIG:FLAG2? to the module. Enter the response. The response should be 1.
