:MEASure :FREQuency :BURSt?PM6680B/81/85
[8 [<expected value>[,<resolution>]] [,<(@«1|2|3|4|5|6|7»)>]]
Burst Carrier Frequency
Measures the carrier frequency of a burst. The burst duration must be less than
50% of the pulse repetition frequency (PRF).
How to measure bursts is described in detail in the Operators Manual.
The counter uses the <expected value> and <resolution> to select a Measurement
Time ([:SENSe]:ACQuisition:APERture), and then sets the sync delay
([:SENSe]:SDELay) to 1.5 * Measurement Time.
Parameters:
<expected value> is the expected carrier frequency,
<resolution> is the required resolution, e.g., 1 gives 1Hz resolution.
<(@«1|2|3|4|5|6|7»)> is the channel to measure on:
(@1) means input A
(@2) means input B (Only PM6680B and PM6681)
(@3) means input C (HF-input option)
(@4) means input E (Rear panel arming input)
(@5) means input A prescaled by 2
(@6) means the internal reference
(@7) means input A with the variable hysteresis mode (Only PM6680B/81)
If you omit the channel, the instrument measures on input A (@1).
