Using TSP
The following TSP code is designed to be run from Keithley Instruments Test Script Builder (TSB).
TSB is a software tool that is available from tek.com/keithley
. You can install and use TSB to write
code and develop scripts for TSP-enabled instruments. Information about how to use TSB is in the
online help for TSB and in the “Introduction to TSP operation” section of the Model DMM6500
Reference Manual.
To use other programming environments, you may need to make changes to the example TSP code.
By default, the DMM6500 uses the SCPI command set. You must select the TSP command set
before sending TSP commands to the instrument.
To enable TSP commands:
1. Press the MENU key.
2. Under System, select Settings.
3. Set the Command Set to TSP.
4. At the prompt to reboot, select Yes.
This sequence of TSP commands makes a series of temperature measurements. After the code
executes, the data is displayed in the Instrument Console of Test Script Builder.
Make sure the TERMINALS switch is set to REAR.
Send the following commands for this example application:
--Reset the instrument to the default settings.
reset()
--Establish variables to make a measurement every 60 seconds 1440 times (24 hours).
local scanCnt = 24 * 60 --1440 minutes = 24 hours
local chanCnt = 9
local totalRdgs = scanCnt * chanCnt
--Empty the buffer and set it to the capacity calculated by totalRdgs.
defbuffer1.clear()
defbuffer1.capacity = totalRdgs
-- Set up the channels to measure temperature using type K thermocouples using
internal reference junction.
channel.setdmm("1:10", dmm.ATTR_MEAS_FUNCTION, dmm.FUNC_TEMPERATURE)
channel.setdmm("1:10", dmm.ATTR_MEAS_UNIT, dmm.UNIT_CELSIUS)
channel.setdmm("1:10", dmm.ATTR_MEAS_NPLC, 1)
channel.setdmm("1:10", dmm.ATTR_MEAS_DIGITS, dmm.DIGITS_5_5)
channel.setdmm("1", dmm.ATTR_MEAS_TRANSDUCER, dmm.TRANS_CJC2001)
channel.setdmm("2:10", dmm.ATTR_MEAS_TRANSDUCER, dmm.TRANS_THERMOCOUPLE)
channel.setdmm("2:10", dmm.ATTR_MEAS_THERMOCOUPLE, dmm.THERMOCOUPLE_K)
channel.setdmm("2:10", dmm.ATTR_MEAS_REF_JUNCTION, dmm.REFJUNCT_EXTERNAL)
-- Set up the scan; channel 2 is first available channel on a 2001-TCSCAN card.
scan.create("2:10")
scan.scancount = scanCnt
-- Set the amount of time for each scan.
scan.scaninterval = 60.0
-- Write the data to a USB flash drive at the end of the scan.
