M-142 Multifunction Calibrator
User Manual v48

Examples:
To set symmetrical squarewave voltage signal, 10V with defined duty cycle:
VOLT 10.0; FUNC :PULS ;
FREQ :DUTY <DNPD>
<cr>
To set digital frequency POS signal with defined duty cycle :
FUNC :PWMP ;
FREQ :DUTY <DNPD>
<cr>
<DNPD>
Represents the duty cycle in percent. 0 to 100% can be set.
If query is sent, M142 returns the set value of the duty cycle using standard exponential format. Example: 25% is
returned as 2.001.
[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, M142 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, M142 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, M142 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
