Performance Verification Tests

NOTE

Zero Offset Verification Test

The procedures in this section are used to test the electrical performance of the digitizer using the specifications in Appendix A as the performance standards.

The Performance Verification Tests are recommended as acceptance tests when the instrument is first received. The performance verification tests should be repeated at each calibration interval following acceptance. If the E1563A or HP E1564A digitizer fails performance verification, adjustment or repair may be needed (see Appendix E).

Performance verification program source code is provided on the Agilent Technologies Universal Instrument Driver CD and are written in ANSI C. The source code files are titled E1563VER.C and E1564VER.C.

This procedure is used to check the zero offset performance of the E1563A or E1564A Digitizer. The digitizer’s internal short is applied to the H (HI) and L (LO) input terminals of the channel being tested using the DIAG:SHORt <channel> command.

1 Check the "Test Conditions" section at the beginning of this appendix.

2Execute DIAG:SHOR1 ON to enable the internal short across the H and L terminals of channel 1.

3Select each range in the order shown in Table D-2. Compare the measurement results to the appropriate test limits shown in the table.
