Fluke PM6681R, PM6685R manual MEASure FREQuency BURSt?, Burst Carrier Frequency

PM6680B/81/85

:MEASure :FREQuency :BURSt?

[￿ [<expected value>[,<resolution>]] [,<(@«1234567»)>]]

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.

<(@«1234567»)> 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).

Complies to standards: SCPI 1992.0, confirmed.
