1594A/1595A Super-Thermometer
Interface Commands
76
Query form: *SRE?
Sets the Service Request Enable register. This mask register determines which corresponding bits of the Status
Byte Register (see Section 8.7.3.7, *STB?, on page 76) affect the MSS master summary bit (bit 6) of the
Status Byte Register and generate a service request from the IEEE-488 port.
8.7.3.7 *STB?
Example response: 16
Reads the Status Byte Register. This indicates any of several events dened by the IEEE-488.2 and SCPI stan-
dards and which are listed in the following table. Reading the Status Byte Register does not affect it.

8.7.3.8 CAL:DATE <year>,<month>,<day>
Example command: CAL:DATE 2009,8,21
Query form: CAL:DATE?
Password protection: unconditional
Sets the instrument’s date of calibration.
8.7.3.9 CAL:PAR:LIN<n> <value>
Query form: CAL:PAR:LIN1?
Password protection: unconditional
Sets a calibration Linearity C<n> parameter.
These settings may be used to apply a linearity correction to the measurement circuit.
IMPORTANT: Calibration parameters should not be changed except as part of the Super-Thermometer
calibration procedure performed by a qualied service technician.
8.7.3.10 CAL:PAR:RES<n> <value>
Query form: CAL:PAR:RES<n>?
Password protection: unconditional
Sets the calibrated resistance of an internal reference resistor. Sufx <n> species the resistor; 1: 1 Ω; 2: 10 Ω;
3: 25 Ω; 4: 100 Ω; 5: 10 kΩ.
IMPORTANT: Calibration parameters should not be changed except as part of the Super-Thermometer cali-
bration procedure performed by a qualied service technician.
8.7.3.11 CAL:PAR:ZERO <value>
Query form: CAL:PAR:ZERO?
Password protection: unconditional
