FRA5087 9-4
9.2 Analysis section input
●
N
umber of output channels 2 channels
●Connector Insulated BNC connector
●Input impedance 1 MΩ
±
2 %, parallel 25 pF  5 pF
●IMRR (isolation mode removal ratio)
120 dB or above (DC up to 60 Hz)
This value applies when the signal source impedance is smaller than 1 Ω.
●Isolation
Withstand voltage 250 Vrms continuous (between signal/ground - enclosure)
250 Vrms continuous (between signal/ground - analysis section input,
between the analysis section channels)
This value applies when the accessory BNC cable is being used.
30 Vrms applies when a cable other than the accessory cable is used.
Against-enclosure capacity No more than 200 pF
●Measurement category I, maximum transient voltage 1,500 Vrms
●Frequency range 0.1 mHz to 10 MHz
●Maximum input voltage 250 Vrms (AC) or  200 V (DC) alternatively  350 Vpeak (AC + DC)
This value applies when accessory BNC cable is used
When a cable other than the accessory cable is used, 30 Vrms
(AC), or
 60 V (DC)
alternatively  42 Vpeak (AC + DC)
●Maximum measurement 250 Vrms
voltage This value applies when the accessory BNC cable is being used.
30 Vrms applies in case a cable other than the accessory cable is used.
●Over detection
Setting range 0 to 250 Vrms
Setting resolution 3 digits
Processes Over lamp lights
Warning sound (can be turned ON/OFF)
Sweep abort (can be enabled/disabled)
Oscillator OFF (can be enabled/disabled)
●Harmonic measurement 2nd to 10th (highest frequency of the harmonics is 10 MHz)
●Harmonic and noise rejection ratio
Normal mode DC 60 dB or above

Harmonic (10th and below) 60 dB or above (analysis frequency 100 kHz or below)
40 dB or above (analysis frequency 100 kHz or below)
●Dynamic range 140 dB typ (10 Hz to 1 MHz)
80 dB typ. (above 1MHz, no more than 10 MHz)
(This value applies when the bigger of the channel inputs is at least 10
Vpeak, with an integration of 4,000 cycles)
●Input weight 0 to 1.0E+6 (resolutions 5 digits or 0.01E-9)
