9764 Oscilloscope Current Probe Adaptor
• Calibrate oscilloscope current probes
• For use with the 5045 scope calibrator
• Compatible with 5025/5051 (with scope option)
• Drive current 0.1mA to 100mA pk-pk
• 0.5% accuracy
• Three interchangeable heads supplied
• Compact design – 142 x 78 x 50mm
• Battery powered (4 x AA cells)
DESCRIPTION
The 9764 current probe adaptor converts the amplitude output of the 5045 oscilloscope calibrator to a square-wave
current in the wire loop of one of three interchangeable heads. Set up is simple, with the oscilloscope current probe
to be calibrated being clamped round the wire loop. It can also be used with the 5025 and 5051 multifunction
calibrators when the oscilloscope calibration option (9770) is fitted.
Ranges
The adaptor is supplied from the amplitude output of the
oscilloscope calibrator with a 1KHz square wave of 0 - 1V pk-pk.
Three heads are supplied with voltage to current conversion
ratios of 100mA / V, 1A/V and 10A/V.
Waveform
The current square wave has slow rounded rising and falling edges
to permit the unit to drive inductive loads without overshoot or
ringing. If the current probe being calibrated introduces excessive
inductance the adaptor compliance limitmay be exceeded, in which
case the compliance error light will come on.
