Incoming Inspection
Incoming Inspection
This section contains functional and 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, and WVR7120 Waveform Rasterizers. The checks are arranged by
model and option so that you can choose the sections that are appropriate 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, since later tests might
depend on items checked in the earlier tests.
Required Equipment
The following equipment is required to perform the incoming inspection
procedures.
