NARDA PMM 9010 Series, User Manual

Page: 108 / 284

10-16 Click Mode Operating Instructions
10.7.8 Max Time
To define the duration of the test it’s enough to enter the relevant time in
minutes in the usual way.
10.7.9 Idle Frequency
Any frequency within the receiver range can be selected for preliminary
investigation in Idle Mode.
0,15 – 0,5 – 1,4 – 30 MHz are the standard channels, preset at the factory,
for the final test procedure.
10.7.10 Idle Level
An arbitrary Level for the Emission Limit can be chosen in Idle Mode, just
to apply a certain tolerance in the debugging phase with respect to the
limit, which will be mandatory at the final test stage.
The threshold level allowed ranges from 31 up to 120 dBµV.
10.7.11 Smart Measure
The “Smart Measure” is a PMM 9010 unique feature, which allows a
relevant time saving in Click measuring approach.
It is usually very difficult to measure QuasiPeak values for pulsed signals,
in a way that linearity of the receiver could normally not fulfill such a special
measurement’s requirement.
PMM 9010 can trace and memorize eventual saturation, instead, just got
during automatic measurement test procedure, in a way that, in case no
saturation conditions at all have been detected, the so got test result can
be used directly to soon calculate the new limit Lq, without the need of
repeating the test for it (that is to say, making possible to skip Step 2, 4, 5
and 6).
At the end of a Smart Measurement, the operator can clearly define if the
test has to be repeated with the new Lq Limit or if not repeating it at all in
case of failure at this first step, so saving time and soon starting with
further debugging of the EUT.
The operator can face then 3 different situations:
-
“No Smart”, where such a function is not used at all;
- “Ask”, where a saturation is detected and the operator is asked to
decide if continuing anyway or not;
- normal “Smart Measure”, where the measurement is normally
performed until the end, i.e. the new Limit Lq is evaluated and the test
is then performed taking such a new Limit into account.
