Rohde & Schwarz CMU 200 - Subsystem Subarrays:multitone

Audio Generator and Analyzer (with Option CMU-B41) CMU

NONE
Interrupt measurement after each statistics cycle
Continue measurement according to its rep. mode
NONE – V3.0
Description of command
This command determines the number of statistics cycles, the stop condition and the stepping mode for the
measurement.
Note: In the case of READ commands (READ:...), the <Repetition> parameter has no effect;
the measurement is always stopped after a single shot.
Subsystem SUBarrays:MULTitone:...
The subsystem SUBarrays:MULTitone:... defines the measurement range and the type of output val-
ues.

Description of command
This command configures the READ:SUBarrays:MULTitone:AF1Channel...,
FETCh:SUBarrays:MULTitone:AF1Channel..., and SAMPle:SUBarrays:MULTitone:AF1Channel
commands. It restricts the measurement to up to 32 subranges where either all measurement results (the num-
ber of which is given by the <Samples> parameter) or a single statistical value is returned.
For <Mode> = IVAL, the <Samples> parameter is ignored and the CMU returns a single measurement value cor-
responding to the abscissa value <Start>. If <Start> is located between two test points with valid results then the
result is calculated from the results at these two adjacent test points by linear interpolation.
The subranges are subsets of the full range of test tones defined via CONFig-
ure:MULTitone:AF1Channel:TONE<nr>. Each subrange contains all test tones between the start test tone
(test tone no. <Start>) and test tone no.
<Start>+<Samples>–1. Test points inside this range that are disabled are not measured (result NAN) and do not
enter into the ARIThmetical, MINimum and MAXimum values.
By default, only one range corresponding to the total measurement range is used and all measurement values
are returned.
