Description
Sets the CW sweep mode number of points of the given channel. Outputs the CW sweep mode number of points of the given channel.
Cmd Parameters
<NRf> The input parameter is a unitless number.

:SENSe{1-16}:SWEep:DELay:TYPe <char1>
:SENSe{1-16}:SWEep:DELay:TYPe?
Description
The command sets the sweep delay type of the indicated channel, as either Off, Load Pulse, or Phase Locked. The sweep delay type definitions are:
LOAD = Load Pulse which sets the sweep so that the sweep starts, and while sweeping, the VNA digital signal processor sends a command to load the programming for the next frequency. At this point, the user-defined delay time period occurs. The sweep-load-delay cycle repeats for every point in the sweep.
LOCK = Phase Locked which sets the sweep delay so that the sweep starts, the hardware frequency phase locks at the point, and then user-defined delay time period occurs. The sweep continues until the sweep is completed.
OFF = The instrument sweeps normally without sweep delay.
The query outputs the sweep delay type of the indicated channel.
Cmd Parameters
<char1> LOCK | LOAD | OFF
Query Parameters
<char1> LOCK | LOAD | OFF
Range
NA
Default Value
OFF

Cmd Parameters
<NRf> The input parameter is a unitless number.
