Models 2510 and 2510-AT Calibration Reference B-9
DAC commands
:IPDac
(:CALibration:PROTected:IPDac)
(:CALibration:PROTected:IPDac:DATA?)
Purpose
To calibrate the current protection DAC.
Format
:cal:prot:ipd
Query
:cal:prot:ipd:data?
Description
The :CAL:PROT:IPD command calibrates the current protection DAC. A
resistor of less than 1.5
Ω
must be connected to the OUTPUT terminals
before this command is sent.
The :CAL:PROT:IPD:DATA? query allows you request the current protec-
tion DAC calibration parameters.
Example
:CAL:PROT:IPD
Calibrate current protection DAC.
RESistance commands
:RESistance
(:CALibration:PROTected:RESistance[:AC])
(:CALibration:PROTected:RESistance[:AC]:DATA?)
Purpose
To calibrate the AC ohms circuit.
Format
:cal:prot:res <Resistance_Value>
Parameters
<Resistance_Value> = 10 to 1e3 [
Ω
] (100 default)
Query
:cal:prot:res:data?
Description
The :CAL:PROT:RES command calibrates the Model 2510 AC ohms cir-
cuit. A 10
Ω
to 1k
Ω
(100
Ω
preferred) resistor must be connected to the
OUTPUT terminals, and the characterized value of that resistor is used as
the :CAL:PROT:RES command parameter. The output is off.
The :CAL:PROT:RES:DATA? query requests the AC ohms calibration
constants.
Example
:CAL:PROT:RES 99.5
Calibrate with 100
Ω
nominal resistor.
