2.1.3 Measurements
Measurement specifications apply to single chassis AC sources. See notes for other models and
configurations. Frequency, VA, power factor and crest factor only apply in AC or AC+DC modes.
Parameter Range Accuracy (± % FS) Resolution
Frequency1 16.00-1000.0 Hz 0.1 % 0.01 Hz to 81.91 Hz
0.1 Hz to 819.1 Hz
1 Hz > 819.1 Hz
Voltage 0 - 400 Volts 0.1 % 0.01 Volt
Current 0 – 15 Amps 0.5 % 0.001 Amp
Peak Current 0 - 60 Amps 0.5 % 0.001 Amp
Crest Factor 1.00 –10.00 1.5 % 0.01
VA Power 0 - 4 KVA 0.5 % 1 VA
Real Power 0 - 4 KW 0.5 % 1 W
Power Factor 0.00 - 1.00 1 % 0.01
Note: Accuracy specifications are valid above 100 counts. For multi-chassis configurations, Current
and Power range and accuracy specifications are times the number of chassis.
Note: Frequency measurement specification valid for output > 20 Vrms.
Note: Crest Factor accuracy applies for Irms > 50% of max.
Note: Power Factor accuracy applies for PF > 0.5 and VA > 50% of max.
2.1.4 Harmonic Measurements
Harmonic measurement specifications apply to 751iX and 1501iX model AC sources only.

Harmonic 2 - 50 0.5% + 0.5%/kHz 0.01A
Note: For multi-chassis configurations, current accuracy specifications are times the number of
chassis.
1 Frequency measurement specifications valid with output voltage of 20Vrms or higher. If output relay is open, frequency
measurement will return 0.0 Hz.
