TAS 200 Series Performance Verification
This section contains procedures to verify that the TAS 220 and TAS 250
oscilloscopes perform as warranted. Verify instrument performance whenever the
accuracy or function of your instrument is in question. The procedures are
organized into four sections: Vertical Check, Horizontal Check, Trigger Check,
and Cursor Check.
The performance verification procedures provide a valid confirmation of
instrument electrical characteristics and function under the following conditions:
H The instrument operates in a 20_ to 30_ C ambient environment.
H The oscilloscope warms up for at least 20 minutes.
H The cabinet remains installed on the oscilloscope.
The performance verification procedure should be performed annually or after
every 2000 hours of operation if used infrequently.
Table 11 lists the equipment needed to do the performance verification proce-
dures.
The TAS 200 series performance verification consists of the checks listed in
Table 10.
