Pulse Definitions

  • D = Delay; the time before each pulse begins

  • W = Width; the time the pulse is ON

  • P = Period; one complete pulse cycle

  • Duty Cycle = W/P

Important: If D + W is greater than P, then undefined PNA behavior results. There is NO error message or warning.

SENSe:PULSe:CATalog?

(Read-only) Returns the string names of internal and configured external pulse generators.

Parameters

None

Examples

SENS:PULS:CAT?

Default

Not Applicable

SENSe<ch>:PULSe<n>:DELay <value>[,<name>]

(Read-Write) Sets the pulse delay. The amount of time before a new pulse begins.

See Pulse Definition diagram.

Parameters

 

<ch>

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

<n>

Internal pulse generator number. Choose from 0 to 4.

0 is the generator that pulses the ADC.

<value>

Delay value in seconds. Choose a value from about 33ns to about 70 seconds.

<name>

Optional. String name of the pulse generator.

Required for use with external pulse generators.

Use SENSe:PULSe:CAT? to return the names of configured pulse generators.

If specified, <n> is ignored.

If unspecified, <n> is required for internal pulse generators.

Examples

Query Syntax

SENSe<ch>:PULSe<n>:DELay? [<name>]

Return Type

Numeric

Default

0

SENSe<ch>:PULSe<n>:DINCrement <value>[,<name>]

(Read-Write) Sets the pulse delay increment. The delay increments with each pulse by the <value> amount.

For example, in this diagram the delay starts as 1.  On the second pulse, delay=2. On the third pulse, delay=3.

Important: If D + W is greater than P, then undefined PNA behavior results. There is NO error message or warning. Delay includes the incremented value.

This is useful for pulse profiling.
