Parameters:
<mode> EQUidistant | ARBitrary
EQUidistant
Sets an equidistant carrrier spacing. The carrier frequency in the
carrier table is not configurable.
ARBitrary
Enables you to specify the carrier frequency in the carrier table.
Carrier spacing is irrelevant.
*RST: EQUidistant
Example:
BB:ARB:MCAR:CARR:MODE EQU
sets an equidistant carrier spacing. The carrier frequency can not
be set.
[:
SOURce<hw>]:BB:ARB:MCARrier:CARRier:SPACing <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 maxi-
mum carrier spacing is limited to Carrier spacing = Total baseband bandwidth /(Num-
ber of carriers - 1).
The total baseband bandwidth is 120 or 60 MHz depending on the installed options.
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 * Out-
putSignalDuration);
Parameters:
<Spacing> float
Range: 0.0 to 120E6
Increment: 0.01
*RST: 0
Default unit: Hz
Example:
BB:ARB:MCAR:CARR:SPAC 10 MHz
sets a carrier spacing of 10 MHz.
[:SOURce<hw>]:BB:ARB:MCARrier:CARRier<ch>:CONFlict?
Queries carrier conflicts. A conflict arises when the carriers overlap.
Return values:
<conflict> 0 | 1 | OFF | ON
*RST: 0
