December 2019 85 LDC-3706 Series Laser Controller
SOURce[1]:RESistance:LCONstants[:GAIN] <nrf> TEC
SOURce[1]:RESistance:LCONstants[:GAIN]?
Description Sets/reports proportional term for TEC controller PID loop in sensor mode.
See Chapter 2 for a summary of PID control.
Parameters 0.000000 – 100.000000 – proportional value setting
Reset Value 15.0
Example SOUR:RES:LCON 15; Sets the proportional term for resistance to 15.
SOURce[1]:RESistance:PROTection:LOW <nrf> TEC
SOURce[1]:RESistance:PROTection:LOW?
Description Sets/reports TE sensor resistance low limit.
Parameters 0.00 – 500000 – Limit in
Reset Value 0.00
Example SOUR:RES:PROT:LOW 0; Sets the resistance low limit to 0.
SOURce[1]:RESistance:PROTection[:HIGH] <nrf> TEC
SOURce[1]:RESistance:PROTection[:HIGH]?
Description Sets/reports TE sensor resistance high limit.
Parameters 0.00 – 500000 – Limit in
Reset Value 40000 (40k)
Example SOUR:RES:PROT:LOW 100000; Sets the resistance high limit to 100k.
SOURce[1]:RESistance:SPOint <nrf> TEC
SOURce[1]:RESistance:SPOint?
Description Sets/reports TE controller resistance setpoint.
Parameters 0.00 – 500000 – Setpoint in
Reset Value 10000
Example SOUR:RES:SPO 10000; Sets the resistance set point to 10k.
SOURce[1]:RESistance:TOLerance <nrf> TEC
SOURce[1]:RESistance:TOLerance?
Description Sets/reports TE controller resistance tolerance. This setting is used in status reporting (see chapter 3). When
the measured resistance is more than this amount over the setpoint, the “Out of Tolerance” bit will be set in the
condition register. The bit will also be set if the measured resistance is less than this amount below the setpoint.
Parameters 0.00 – 500000.0 – Tolerance in
Reset Value 5000.0
Example SOUR:RES:TOL 7500.0; Sets the resistance tolerance to 7.5k.
