USING THE COMBISCOPE INSTRUMENTS

3.11.2.1Readout of measurement data

The DISPlay:WINDow[1]:TEXT<n>:DATA? query allows you to acquire measured data as displayed on the upper line(s) of the screen of your CombiScope instrument. The following measured data values can be selected by specifying the number <n> in the query:

NUMBER <n>:

MEASUREMENT VALUE:

1, 2

MEAS1, MEAS2 data

10, 11, 12, 13, 20, 21,

 

30, 40, 51, 52

CURSORS data

60, 61

MATH - FFT frequency, amplitude

MEAS1/MEAS2 DATA:

The MEAS1 and MEAS2 functions must be enabled and selected via front panel control. MEAS1 data is read by sending the DISPlay:WINDow:TEXT1:DATA? query and MEAS2 data by sending the DISPlay:WINDow:TEXT2:DATA? query, followed by reading the response strings.

The format of a response string is as follows:

<meas_type>,<meas_value>,<suffix_unit>
