<Rate>
Sets/queries the clock rate (frequency) for signal transmission between the R&S
EX-IQ-
BOX and the external device (DUT). Depending on the logic type and the clock source
the clock rate range varies).

1 kHz represents the internal clock source, fed in from the R&S Instrument, 25 kHz are given from the
external reference at the user interface.
Note:
The value range of the clock rate depends on
Protocol
,
Logic Type
and
Signal
Type
settings.
Parameters:
<Rate>
float
Range:
1 kHz to 400 MHz
*RST:
10 MHz
Example:
SOUR1:EBOX:USER:CLOC:RATE?
query the current frequency of the clock signal of the R&S
EX-IQ-
BOX.
SOUR1:EBOX:USER:CLOC:RATE 10MHZ
set the clock rate of the R&S
EX-IQ-BOX to 10 MHz.
