Incoming Inspection
Incoming Inspection
This section contains functional a nd operational checks appropriate to an
incoming inspection.
The waveform rasterizer must have been operating for a warm-up period of at
least 20 minutes, and must be operating at an ambient temperature as listed in
the table. (
See Table 20 on page 11.)
Use the following procedures to check the basic functionality of WVR6020,
WVR7020, a
nd WVR7120 Waveform Rasterizers. The checks are arranged by
model and option so that you can choose the sections that are a ppropriate for your
instrument. The last two sections are for less critical waveform rasterizer features:
the ground closure and Ethernet ports. You need only test these if you intend to
use them. In general, you should test in the order presented, sinc e l ater tests might
depend on items checked in the earlier tests.
