598 Operating Manual 1403.7458.32 ─ 14
Parameters:
<Count> integer
Range:
1 to 512
*RST: 1
Example: BB:ARB:MCAR:CARR:COUN 10
sets 10 carriers for the multi carrier waveform.
Manual operation: See "Number of Carriers" on page 414
[:SOURce<hw>]:BB:ARBitrary:MCARrier:CARRier:MODE <Mode>
The command sets the carrier frequency mode.
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.
Manual operation: See "Mode" on page 413
[:SOURce<hw>]:BB:ARBitrary:MCARrier:CARRier:SPACing <Spacing>
The command sets the frequency spacing between adjacent carriers of the multi car-
rier 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 unmodu-
lated.
●
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);
