
Maximum input voltage 600 V CAT II or 300 V CAT III (BNC signal to BNC ground)
Below 45 Hz: 600 Vpk (AC + DC)
45 Hz to 100 kHz: 600 Vrms (AC)
100 kHz to 2 MHz: 600 Vrms (AC) × 100 ÷ F
where F is frequency in units of kHz.
At 45 Hz and above, the voltage including DC must be 600 Vrms or less and
849 Vpk or less.

IMRR (isolation mode rejection ratio)
120 dB or more (DC to 60 Hz)
Conditions: Input shorted, integration 200 cycles or more, and common mode
voltage 10 Vpk

Isolation 600 V CAT II or 300 V CAT III (BNC ground to enclosure)
Below 45 Hz: 600 Vpk (AC + DC)
45 Hz to 100 kHz: 600 Vrms (AC)
100 kHz to 2 MHz: 600 Vrms (AC) × 100 ÷ F
where F is frequency in units of kHz.
At 45 Hz and above, the voltage including DC must be 600 Vrms or less and
849 Vpk or less.
