Levels of Testing
VX4792 User Manual
This section contains a series of procedures to verify that the VX4792 Arbitrary
Waveform Generator performs as warranted. The procedures are arranged in nine
logical groupings, presented in the following order:
H Operating Mode Checks
H External AM Operation Check
H Clock Frequency and Amplitude Checks
H Gain and Offset Accuracy Checks
H Pulse Response Check
H SYNC OUTPUT and MARKER OUTPUT Amplitude Checks
H External Trigger Level Accuracy Check
H External CLOCK IN Check
H Synchronous Operation Check
Before you perform the performance verification procedures, you must complete
the System Setup located on page F–8.
Two levels of performance testing are available to test the waveform generator.
The test you perform depends upon your requirements. The tests are described
below.
Functional Check Procedure. This procedure, located on page 1–11, tests the
installed module to verify that it is operating properly. Once the waveform
generator is installed into a VXIbus mainframe with a suitable computer
interface, no additional test equipment is needed to perform the functional check.
The Functional Check Procedure is short, requires no external equipment, and
performs extensive functional and accuracy testing. Use this check to quickly
determine if the waveform generator is suitable for putting into service, such as
when it is first received.
Performance Verification Procedures. This group of procedures, which begin on
page F–11 with Operating Mode Checks, provides a more extensive test to verify
performance of the waveform generator. The procedures involve direct checking
of warranted specifications. The procedures require more time than the Function-
al Check Procedure, and external test equipment is required (see Equipment
Required on page F–3). Use the performance verification procedures to verify
that the waveform generator performance is within warranted limits.
