Boonton55xxx IVI Driver Reference

BTN55XXX_ATTR_PULSE_UNITS Attribute
Pulse See Also

Set or return the units for entering the pulse distal, mesial and proximal levels.

Attribute Tree Node: \Boonton55xxx\Instrument Specific\Channel\Pulse\Pulse Units

Declaration: Btn55xxx.h

Implementation: Btn55xxx.dll

Visual C++

#define BTN55XXX_ATTR_PULSE_UNITS 1150036
ViStatus Btn55xxx_GetAttributeViInt32(
ViSession Vi,
ViConstString RepCapIdentifier,
ViAttr AttributeID,
ViInt32* AttributeValue
);
ViStatus Btn55xxx_SetAttributeViInt32(
ViSession Vi,
ViConstString RepCapIdentifier,
ViAttr AttributeID,
ViInt32 AttributeValue
);

Parameters

The ViSession handle that you obtain from the IviDriver_init or IviDriver_InitWithOptions function. The handle identifies a particular instrument session.

RepCapIdentifier

A physical or virtual repeated capability identifier. For valid values, see the Channel repeated capability.

AttributeID

Must be BTN55XXX_ATTR_PULSE_UNITS.

AttributeValue (GetAttribute)

Returns the current value of the attribute. The user must specify the address of a variable that has the same data type as the attribute.

AttributeValue (SetAttribute)

The value to which to set the attribute.

Remarks

If the function is set to VOLTS, the pulse transition levels will be defined as the specified percentage in voltage. If set to WATTS, the levels are defined in percent power. Many pulse measurements call for 10% to 90% voltage (which equates to 1% to 81% power) for risetime and falltime measurements, and measure pulse widths from the half-power (-3dB, 50% power, or 71% voltage) points.

Instrument Command

SENSe{Channel}:PULSe:UNIT {WATTS|VOLTS}

SENSe{Channel}:PULSe:UNIT?

Defined Values

Name	Description
BTN55XXX_VAL_PULSE_UNITS_WATTS	The levels are defined in percent power.
BTN55XXX_VAL_PULSE_UNITS_VOLTS	The pulse transition levels will be defined as the specified percentage in voltage.
