HP E1586A Rack Mount Terminal Panel

Example Using a Single

Terminal Panel:

SENS:REF THER,5000,1,(@100,101,102)

measures reference temperature measurements on channels 100 to 102

SENS:FUNC:TEMP TC,K,.06,(@103:131)

defines channels for temperature measurements

ROUT:SEQ:DEF (@100,103:107,101,108:123,102,124:131)

defines the scan list

Example Using Two

Terminal Panels:

SENS:REF THER,5000,1,(@100,101,102,132,133,134)

measures reference temperature measurements on channels 100 to 102

SENS:FUNC:TEMP TC,K,.06,(@103:131,135:163)

defines channels for temperature measurements

ROUT:SEQ:DEF (@100,103:107,101,108:123,102,
124:131,132,135:139,133,140:155,134,156:163)

defines the scan list

Note that each reference channel (100, 101, 102, 132, 133, 134) immediately
precedes its associated measurement channels in the scan list.
