Measurement
Generator Output ..................................................RF leakage: from active electrode or neutral plate with an open or closed load circuit
Mode of Operation ................................................Manual or user-programmable. Control remotely with PC utilizing accessory Ansur QA-ES
Plug-in software and RS232 communication cable connection.
Measurements .......................................................True RMS value of applied waveform
RMS Bandwidth.....................................................30 Hz to 10 MHz (-3 dB) for instrumentation only; 30 Hz to 2.5 MHz (-3 dB) with loads
Low Frequency Filter ............................................100 Hz filter to avoid low frequency disturbance and/or interference
Current ...................................................................20 mA to 2200 mA
Current Accuracy ..................................................20 to 2200 mA ±2 % of reading
Load Resistance....................................................10 to 2500 Ω in steps of 25 Ω (at dc); 2500 to 5200 Ω in steps of 100 Ω (at dc)
10 Ω at 100 W for 30 seconds, 15 % duty cycle
25 to 50 Ω at 200 W for 30 seconds, 15 % duty cycle
75 to 2975 Ω at 400 W for 30 seconds, 15 % duty cycle
≥
3000 Ω at 70 W for 30 seconds, 15 % duty cycle
all load resistances at 500 W for 5 seconds, 10 % duty cycle
Additional Fixed Load...........................................200 Ω, 400 W maximum for 30 seconds, maximum 15 % duty cycle
Crest Factor ...........................................................The Analyzer uses the higher of the two peak measurements for calculation.
Range .....................................................................1.4 to 16 (V peak voltage / V RMS)
Foot Switch Output ...............................................The output triggers the measurement after a programmed delay time, defined as the time
from the activation of the foot switch to the beginning of data processing. The delay time
is 200 ms to 4000 ms.
Peak-to-Peak Voltage............................................0 to 10 kV (closed load only) Accuracy ±10 %. The Analyzer takes a measurement
between the active and dispersive electrodes with closed load only.
Volt-Hertz Product.................................................10
9
Oscilloscope Output .............................................5 V/A uncalibrated, 100 mA RF current minimum input
