[SOUR] :FREQ :VOLT (?) <DNPD>
This command sets the amplitude of PWMP, PWMS, PWMN signals.
Examples:
To set the amplitude of PWMP digital frequency signal:
FUNC :PWMP ;
FREQ :VOLT <DNPD>
<cr>
<DNPD>
Represents the voltage in Volts. 0.000 to 10.000 V can be set.
If query is sent, M140 returns the set value of the amplitude using standard exponential format. Example: 2.05V
is returned as 2.000.
[SOUR] :FREQ :ATTE (?) <DNPD>
This command sets the attenuation of digital SQU frequency signal.
Examples:
To set the attenuation of high frequency signal:
FUNC :SQU ;
FREQ :ATTE <DNPD>
<cr>
<DNPD>
Represents the attenuation in decibels. 0 to -30 dB can be set in 10 dB increments.
If query is sent, M140 returns the set value of the attenuation using standard exponential format. Example: -20 dB
is returned as -2.001.
[SOUR] :TEMP :UNIT (?) <CPD> { C | CEL | K }
This command sets the unit of measurement of temperature.
•
C or CEL sets „Centigrade“
•
K sets „Kelvin“
The unit of measurement remains valid after the calibrator is switched off.
If query is sent, M140 returns the set unit of measurement{ C | K }.
[SOUR] :TEMP :SCAL (?) <CPD> { TS68 | TS90 }
This command sets one of temperature scales. The setting influences the simulation of resistance temperature
sensors and thermocouples.
•
TS68 sets IPTS-68 temperature scale
•
TS90 sets ITS-90 temperature scale
The temperature scale remains valid after the calibrator is switched off.
If query is sent, M140 returns the set temperature scale { TS68 | TS90 }.
[SOUR] :TEMP :THER [:LEVE] [:IMM] [:AMPL] (?) <DNPD>
This command activates the simulation of thermocouples (DC voltage generation).
<DNPD>
Represents the temperature expressed in the units set by the ‘UNIT’ command. “Technical Data” chapter lists the
acceptable ranges.
If query is sent, M140 returns the set temperature using standard exponential format. Example: 20.5
C is returned
as 2.001.
