[:SOURce<hw>]:BB:MCCW:CARRier:SPACing <Spacing>
The command sets the carrier spacing.
The carriers are generated symmetrically around the center carrier. The total bandwidth
is calculated as ("Number of carriers" - 1) * "Carrier spacing "and must not exceed the
system bandwidth of the instrument (see data sheet).
The maximum carrier spacing that can be set is dependent on the chosen number of
carriers
The maximum carrier spacing is automatically reduced so that the maximum total band-
width is not exceeded on entering the number of carriers
(:BB:MCCW:CARRier:COUNt).
Parameters:
float
0 Hz to 50 MHz
0.01 Hz
10 kHz
<Spacing>
Range:
Increment:
*RST:
BB:MCCW:CARR:SPAC 10 MHz
sets a carrier spacing of 10 MHz.
Example:
[:SOURce<hw>]:BB:MCCW:CARRier:STATe <CarrierIndex>,<State>
[:SOURce<hw>]:BB:MCCW:CARRier:STATe? <CarrierIndex>
The command switches the selected carrier on or off.
The counting in remote control differs from the numbers in the carrier table. Index 0 cor-
responds to number 1 (first line) in the table. Therefore, switching the state of the channel
via remote control always switches the state of <channel index> + 1 in the table.
Setting parameters:
0|1|OFF|ON
ON
Parameters for setting and query:
float
Determines the carrier number.
0 to Max Number of Carriers
<State>
*RST:
<CarrierIndex>
Range:
BB:MCCW:CARR:STAT 15, ON
switches carrier 16 on.
Example:
[:SOURce<hw>]:BB:MCCW:CFACtor <Cfactor>
The command sets the desired crest factor for the multi carrier signal on selection of the
command SOUR:BB:MCCW:CFAC:MODE SLOW.
