Test condition for Measurement Time
The measurement time of E4982A is scattered to some extent by an overhead of the internal operation system and other
conditions, so it is difficult to define the specification of handler interface timing. Thus, for your reference, we provide
“SPD” data on it in table by defining the following test condition.
Median: Median value of running one minute of measurement data
Max.: Maximum value of running one minute of measurement data
NOTE
1. The instrument’s operating system sometimes suffers interruptions during measurement, and we sometimes observe
an extremely large overhead in handler interface timings. The table excludes such special cases, thus you can
sometimes see timing over the maximum value data shown in the table. If you make a handshake using the
READY_FOR_TRIGGER signal of the handler interface, your test system can continue to work correctly regardless of
such an irregular measurement time drift.
2. If your system communicates with external devices, you will see longer timing results than those on the table.
3. In the case of using a bus trigger in the GPIB/LAN/USB system instead of the handler interface, you should measure
the test cycle time for yourself, because the system performance depends heavily on the system parameters.
Of course, you will see much longer test cycle times from your system software overhead.
