Click Mode Operating Instructions
To define the duration of the test it's enough to enter the relevant time in
minutes in the usual way.
A frequency (0,15 – 0,5 – 1,4 – 30 MHz) can be selected for preliminary
investigation in Idle Mode.
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 "Smart Measure" is a PMM 9010 unique feature which allows a
relevant time saving in Click measuring approach.
It's 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.
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 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.
