CALIBRATION TW SERIES
3-32
Program the TW to 160 Hz using the string below:
SOUR {1,2,3} :FREQ 160
Wait until the power analyzer has stabilized and record the current reading as RDNG3 .
Query the TW’s current using the GPIB string below, and record this value as MEAS3 .
MEAS {1,2,3} :CURR?
Program the TW to 320 Hz using the string below:
SOUR {1,2,3} :FREQ 320
Wait until the power analyzer has stabilized and record the current reading as RDNG4 .
Query the TW’s current using the GPIB string below, and record this value as MEAS4 .
MEAS {1,2,3} :CURR?
Program the TW to 500 Hz using the string below:
SOUR {1,2,3} :FREQ 500
Wait until the power analyzer has stabilized and record the current reading as RDNG5 .
Query the TW’s current using the GPIB string below, and record this value as MEAS5 .
MEAS {1,2,3} :CURR?
Program the TW to 60 Hz and open the output relay using the strings below:
SOUR {1,2,3} :FREQ 60
OUTP OFF
Calculate the calibration constants using the following equations:
VALUE1 = RDGN1 / MEAS1
VALUE2 = RDGN2 / MEAS2
VALUE3 = RDGN3 / MEAS3
VALUE4 = RDGN4 / MEAS4
VALUE5 = RDGN5 / MEAS5
