Description

Specifies the polarity of the trigger IN signal.

• AuxTrigger Object - Sets the polarity to which the rear-panel AuxTrig IN responds.

• PulseGenerator Object - Sets the polarity of trigger to which the internal pulse generators will respond when being externally triggered. Note: This feature requires DSP version: 4.0 FPGA:34 or higher. Learn more.

Note: Used on PNA-X ONLY.

 VB Syntax

object.TriggerInPolarity = value

Variable

(Type) - Description

object

An AuxTrigger (object) or

A PulseGenerator (object)

value

(enum NATriggerPolarity) - Choose from:

naTriggerPositive  VNA responds to rising edge or HIGH level

naTriggerNegative  VNA responds to falling edge or LOW level.

Set Edge or Level triggering using TriggerInType Property

Return Type

Enum

Default

AuxTriggerIn Object - naTriggerNegative

PulseGenerator Object - naTriggerPositive. Also the polarity used when the PNA-X does not have the required DSP hardware

Exaamples

obj.TriggerInPolarity = naTriggerPositive 'Write

value = obj.TriggerInPolarity 'Read the value

C++ Syntax

HRESULT get_TriggerInPolarity(enum NATriggerPolarity *val);
HRESULT put_TriggerInPolarity(enum NATriggerPolarity val);
