Arb Commands
Two Tone Subsystem–N5172B/82B ([:SOURce]:RADio:TTONe:ARB)
NOTE A waveform file that has unspecified settings in the file header uses the previous waveform’s
routing settings. This could create the situation where there is no RF output signal, because
the previous waveform used RF blanking
For more information on the marker RF blanking function, see the User’s Guide.
NONE This terminates the marker RF blanking/pulse function.
M1–M4 These are the marker choices. The RF blanking/pulse feature uses only one marker
at a time.
*RST NONE
:MPOLarity:MARKer1|2|3|4
Supported N5172B/82B
[:SOURce]:RADio:TTONe:ARB:MPOLarity:MARKer1|2|3|4 NEGative|POSitive
[:SOURce]:RADio:TTONe:ARB:MPOLarity:MARKer1|2|3|4?
This command sets the polarity for the selected marker.
For a positive marker polarity, the marker signal is high during the marker points. For a negative
marker polarity, the marker signal is high during the period of no marker points. To configure marker
points, refer to the following sections located in the Dual ARB subsystem:
• For clearing a single marker point or a range of marker points, see“:MARKer:CLEar” on page 281.
• For clearing all marker points, see “:MARKer:CLEar:ALL” on page 282.
• For shifting marker points, see “:MARKer:ROTate” on page 282.
• For information on markers and setting marker points, see “:MARKer[:SET]” on page 283.
Example
:RAD:TTON:ARB:MPOL:MARK1 POS
The preceding example sets the polarity for marker one to positive.
*RST POS
:NOISe:BANDwidth
Supported N5172B/82B with Option 403
[:SOURce]:RADio:TTONe:ARB:NOISe:BANDwidth <val><unit>
[:SOURce]:RADio:TTONe:ARB:NOISe:BANDwidth?
This command sets the flat noise bandwidth value for the two- tone waveform. This value is typically
set wider than the carrier bandwidth.
