8.3 Using Analog and Waveform D/A Output
168
• Output signals are waveforms of the instantaneous values of input voltages and currents.
• Voltage inputs and current sensor inputs are mutually isolated.
• Combine with an oscilloscope to observe waveforms of phenomena such as device inrush current.
About Waveform Outputs
Specifications
Output voltage Select from either ±1 V or ±2 V, crest Factor 2.5 or higher
Output impedance 100 ±5
Output update rate 500 kHz
• D/A1: U1, D/A2: I1, D/A3: U2, D/A4: I2, D/A5: U3, D/A6: I3, D/A7: U4, D/A8: I4
• Waveform clipping occurs at approximately
±7 V.
• Maximum output voltage that can possibly be output from malfunction, etc. is approximately
±12 V.
• When using VT or CT ratio, the instrument outputs a voltage that is obtained by multiplying
the range by the VT or CT ratio.
• Waveform output consists of uninterrupted instantaneous values, regardless of data hold,
peak hold, or averaging operations.
• When auto-ranging is enabled, the analog output levels change with auto-ranging. Be careful
to avoid range conversion mistakes when measuring rapidly fluctuating values. Such mis-
takes can be avoided by using a fixed range. It is recommended to use a fixed range for this
type of measurement.
