(Read-only) Reads whether the specified channel is currently 'blocked' from sweeping. Learn more about the Mechanical Devices dialog.

Parameters

<cnum>

Any existing channel number. If unspecified, value is set to 1

Examples

SENS:SWE:BLOC?

sense2:sweep:blocked?

Return Type

Boolean

0 - No, the channel is NOT blocked.

1 - Yes, the channel is blocked.

Default

N/A

(Read-Write) Sets the dwell time between each sweep point.

• Dwell time is ONLY available with SENSe:SWEep:GENeration set to STEPped; It is Not available in ANALOG.

• Sending dwell = 0 is the same as setting SENS:SWE:DWEL:AUTO ON. Sending a dwell time > 0 sets SENS:SWE:DWEL:AUTO OFF.

Parameters

<cnum>

Any existing channel number. If unspecified, value is set to 1

<num>

Dwell time in seconds.

This command will accept MIN or MAX instead of a numeric parameter. See SCPI Syntax for more information.

Examples

SENS:SWE:DWEL .1
sense2:sweep:dwell min

Query Syntax

SENSe<cnum>:SWEep:DWELl?

Return Type

Numeric

Default

0 - (Note: dwell time set to 0 is the same as dwell:auto ON)

(Read-Write) Specifies whether or not to automatically calculate and set the minimum possible dwell time. Setting Auto ON has the same effect as setting dwell time to 0.

Parameters

<cnum>

Any existing channel number. If unspecified, value is set to 1

<ON | OFF>

ON (or 1) - turns dwell ON.
OFF (or 0) - turns dwell OFF.

Examples

SENS:SWE:DWEL:AUTO ON
sense2:sweep:dwell:auto off

Query Syntax

SENSe<cnum>:SWEep:DWELl:AUTO?

Return Type

Boolean (1 = ON, 0 = OFF)

Default

ON

(Read-Write) Specifies the time to wait just before acquisition begins for each sweep. This delay is in addition to Dwell Time and the following two External Trigger delays if enabled.

• Trig:Delay (global scope)

• Sens:Swe:Trig:Delay  (channel scope)

Parameters

<cnum>

Any existing channel number. If unspecified, value is set to 1

<num>

Sweep delay in seconds.

This command will accept MIN or MAX instead of a numeric parameter. See SCPI Syntax for more information.

sense2:sweep:dwell:sdelay .5

Query Syntax

SENSe<cnum>:SWEep:DWELl:SDELay?

(Read-Write) Sets sweep as Stepped or Analog.

Parameters

<cnum>

Any existing channel number. If unspecified, value is set to 1

<char>

Choose from:

STEPped - source frequency is CONSTANT during measurement of eah displayed point. More accurate than ANALog. Dwell time can be set in this mode.

ANALog - source frequency is continuously RAMPING during measurement of each displayed point. Faster than STEPped. Sweep time (not dwell time) can be set in this mode.

SENSe<cnum>:SWEep:GENeration?

Return Type

Character

Default

Analog

Parameters

<cnum>

Any existing channel number. If unspecified, value is set to 1

<char>

Trigger mode. Choose from:

HOLD - channel will not trigger

CONTinuous - channel triggers indefinitely

GROups - channel accepts the number of triggers specified with the last SENS:SWE:GRO:COUN <num>. This is one of the PNA overlapped commands. Learn more.

SINGle - channel accepts ONE trigger, then goes to HOLD.

Note: To perform simple, single-triggering, use SINGle which requires that TRIG:SOURce remain in the default (internal) setting.

(Read-Write) Sets and reads the trigger delay for all measurements in the specified CHANNEL. This delay is only applied while TRIG:SOURce EXTernal and TRIG:SCOP CURRent .  After an external trigger is applied, the start of the sweep is delayed for the specified delay value plus any inherent latency.

To apply a trigger delay for all channels (Global), use TRIG:DEL

Parameters

<cnum>

Any existing channel number. If unspecified, value is set to 1

<num>

Trigger delay value in seconds. Range is from 0 to 3 seconds

Examples

Default

0

(Read-Write) Sets and reads the trigger mode for the specified channel. This determines what EACH signal will trigger.  Learn more.

Note: Setting Point and Sweep mode forces Trigger:SCOPe = CURRent

Parameters

<cnum>

Any existing channel number. If unspecified, value is set to 1

<char>

Trigger mode. choose from:

• CHANnel - Each trigger signal causes ALL traces in that channel to be swept.

• SWEep - Each Manual or External trigger signal causes ALL traces that share a source port to be swept.

• POINt -- Each Manual or External trigger signal causes one data point to be measured.

• TRACe - Allowed ONLY when SENS:SWE:GEN:POIN is enabled. Each trigger signal causes two identical measurements to be triggered separately - one trigger signal is required for each measurement. Other trigger mode settings cause two identical parameters to be measured simultaneously.

Examples

SENS:SWE:TRIG:MODE SWE
sense2:sweep:trigger:mode point

Query Syntax

SENSe<cnum>:SWEep:TRIGger:MODE?

Return Type

Character

Default

Channel

This command is replaced with SENS:SWE:TRIG:MODE POINT

<ON | OFF>

ON (or 1) - Channel measures one data point per trigger.

OFF (or 0) - All measurements in the channel made per trigger.
