About Data Format

Description

Sets and returns the units for the specified data format.  Measurements with display formats other than those specified are not affected.

 VB Syntax

meas.FormatUnit (format) = value

Variable

(Type) - Description

meas

A Measurement (object)

format

(enum NADataFormat) - Choose from:

0 - naDataFormat_LinMag

1 - naDataFormat_LogMag

value

(enum naFormatUnit)

For LogMag, choose from:

• 0 - naFormatUnit_dBm  Units are displayed in dBm.  0 dBm = 0.001 watt

• 1 - naFormatUnit_dBmV  Units are displayed in dBmV.  0 dBmV = 0.001 volt
  DBmV value depends on the reference impedance: dBmV = dBm + 30 + 10*log10(Z0)

• 2 - naFormatUnit_dBmA  Units are displayed in dBmA.  0 dBmA = 0.001 Ampere

• 6 - naFormatUnit_dBuV  Units are displayed in dBuV.  0 dBuV = 1 uV
  DBuV value depends on the reference impedance: dBuV = dBm + 90 + 10*log10(Z0)

For LinMag, choose from:

• 3 - naFormatUnit_W - Watts

• 4 - naFormatUnit_V - Volts

• 5 - naFormatUnit_A - Amperes

Return Type

Enum

Default

0 - naFormatUnit_dBm

Examples

meas.FormatUnit(1)= naFormatUnit_dBmV 'Write

units = meas.FormatUnit(1) 'Read

C++ Syntax

HRESULT put_FormatUnit(tagDataFormat format, tagFormatUnit unit)

HRESULT get_FormatUnit(tagDataFormat format, tagFormatUnit* unit)
