The rms level is calculated with the formula:
RMS [dB] = Peak [dB] - Crest Factor [dB] + Gain [dB]
The crest factor must correspond to the input signal. Enter the value, e.g. a connected
baseband generator provides.
Note: Crest factor applies to external signals, i.e. to digital standards or to user defined
signals. If the R&S EX-IQ-BOX is working with an internal signal, that is generated by a
pattern or a waveform file, the parameter is already known must not be entered manually.
Parameters:
<Crest> float
Range:
0 to 30
Increment: 0.01
*RST:
0
Default unit: dB
Example: SOUR1:EBOX:CPRI:TX:SIGN:CRES 10dB
set the 10 dB crest factor.
Manual operation: See "Crest Factor" on page 180
[:SOURce<hw>]:EBOX:CPRI:TX|RX:SIGNal<ch>:DELete
Removes a signal from the list. The function removes the corresponding AxCs from the
list of used AxCs. The signal is selected by the index
<ch>
.
Example: SOUR1:EBOX:CPRI:TX:SIGN2:DEL
removes the second signal from the list of downlink signals.
Usage: Event
Manual operation: See "Delete" on page 173
[:SOURce<hw>]:EBOX:CPRI:TX|RX:SIGNal<ch>:GAIN <Gain>
Sets a gain value for the I/Q signal. Positive values lead to a digital signal amplification,
and negative values correspond to a digital signal attenuation. A gain value of 0
dB results
in an unchanged level of the I/Q signal. By default, the value is set to 0 dB.
Parameters:
<Gain> float
Range:
-40 to 6
Increment: 0.01
*RST:
0
Default unit: dB
Example: SOUR1:EBOX:CPRI:TX:SIGN:GAIN -20
set -20 dB gain.
Manual operation: See "Gain" on page 179
