FRA 51602
Capacitance relative to enclosure 200 pF or less

Frequency range 10 µHz to 2 MHz

Maximum measurement voltage
600 Vrms
When the provided signal cable is used.
When the other signal cables are used, the voltage is restricted to the rated
voltage of the cable or to 600 Vrms, whichever is less.

Over-level detection
Setting range 0 to 600 Vrms
Setting resolution 3 digits
Processing Over lamp lights.
Buzzer warning sound (can be turned on / off)
Stop sweep measurement (can be turned enable / disable)
Over-level detection occurs when the amplitude or maximum measurement input voltage that is set as
described above is exceeded. (See "
9.2 Analysis input section
, ● Measurement range”.)

Dynamic range 140 dB (10 Hz to 1 MHz)
80 dB (1 MHz to 2 MHz)
The maximum measurable gain, limited by the noise floor and cross talk
between channels.
Conditions: The larger channel input is at least 10 Vpk, integration is 300
cycles, and the measurement range is AUTO for both channels.

Input weighting Setting range is 0 to 1.12, resolution 6 digits or 1E-12
CH1 and CH2 are set independently
The weight is a coefficient that is applied to measurement results of CH1 or
CH2 to correct the attenuation or gain of probes, amplifiers, or other such
equipment that is connected to the instrument.

Phase inversion function ON or OFF
This function is used when the polarity of connection to the circuit being
tested is reversed.
The isolation specifications for between the oscillator ( OSC ) and analysis input ( CH1 or CH2 ) and the
instrument enclosure is illustrated in Figure 9-1 . The isolation specifications between the OSC , CH1 , and
CH2 signal connectors is illustrated in Figure 9-2 .
