High Range Current Frequency Calibration - Cal Power TrueWave TW5250 Service Manual

SERVICE MANUAL

3.28 HIGH RANGE CURRENT FREQUENCY CALIBRATION

Connect the 48 ohm resistor to the output of the TW through the power analyzer. Set
up the power analyzer to measure current.
Set up the TW to AC coupling, low range, remote sense, 40 Hz, 6.5 ampere current
limit, output relay closed and 240 volts with the following GPIB programming strings:
OUTP:COUP AC
SOUR:VOLT:RANGE HIGH
SOUR:SENSE REMOTE
SOUR:FREQ 40
SOUR{1,2,3}:CURR 6.5
OUTPUT ON
SOUR{1,2,3}:VOLT 240
Wait until the power analyzer has stabilized and record the current reading as RDNG1.
Query the TW's current using the GPIB string below, and record this value as MEAS1.
MEAS{1,2,3}:CURR?
Program the TW to 80 Hz using the string below:
SOUR{1,2,3}:FREQ 80
Wait until the power analyzer has stabilized and record the current reading as RDNG2.
Query the TW's current using the GPIB string below, and record this value as MEAS2.
MEAS{1,2,3}:CURR?
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.
