Remote Control Commands
SOURce:BB:ARB:MCAR Subsystem
[:SOURce]:BB:ARBitrary:MCARrier:CARRier:SPACing
The command sets the frequency spacing between adjacent carriers of the multi carrier
waveform. The carriers are generated symmetrically around the RF carrier. The maximum
carrier spacing is limited to Carrier spacing = Total baseband bandwidth /(Number
of carriers - 1).
The total baseband bandwidth is 80 MHz.
Note:In order to avoid wrap-around problems, the effective "Carrier Spacing" might be
slightly modified. The "Carrier Spacing" is rounded in that way that the carrier closest to
the center RF frequency shows no phase jump assuming that the carrier is unmodulated.
●
●
For odd number of carriers:
RoundedCarrierSpacing=1/OutputSignalDuration* round(CarrierSpacing * Output-
SignalDuration);
For even number of carriers:
RoundedCarrierSpacing=2/OutputSignalDuration*round(0.5 *CarrierSpacing * OutputSignalDuration);
Parameters:
Example:
float
Range: 0.0 to 120E6
Increment: 0.01
*RST: 0
Default unit: Hz
BB:ARB:MCAR:CARR:SPAC 10 MHz
sets a carrier spacing of 10 MHz.
Manual operation: See "Carrier Spacing" on page 95
[:SOURce]:BB:ARBitrary:MCARrier:CARRier:CONFlict?
Queries carrier conflicts. A conflict arises when the carriers overlap.
Return values:
Example:
0 | 1 | OFF | ON
*RST: 0
BB:ARB:MCAR:CARR2:CONF?
queries the multi carrier conflict state.
Response: 0 no conflict has occurred.
Usage:
Query only
Manual operation: See "Carrier Table" on page 103
[:SOURce]:BB:ARBitrary:MCARrier:CARRier:DELay
The command sets the start delay of the selected carrier.
