SPECIFICATIONS

NUMBER CHANNELS 8

ANALOG INPUTS

Input signal range: ±10V DC minimum linear range.

±12 V typical working range.

Safe input voltage: ±30 V power on. ±15 V power off.

Input resistance: 1 MΩ.

Input capacitance: 45 pF.

ANALOG OUTPUTS

Output signal range: ±10 V minimum, ±12 V typical, at BNC and Link

outputs.

±1 V minimum, ±1.2 V typical, at recorder output.

Output impedance: Approximately 420 Ω in series with the output;

3,300 pF to ground. (Forms a passive 115 kHz

low-pass filter.)

Output short-circuit duration: Indefinite.

Output offset: < ±20 mV. Automatically calibrated.

Offset calibration: Offset on individual channels is calibrated after gain

changes and input coupling changes. Offset on all

channels is automatically calibrated 5 minutes after

power is switched on.

AMPLIFICATION

Total gain: x1, 2, 5, 10, 20, 50, 100, 200, 500, 1k, 2k, 5k, 10k,

20k.

Pre-filter gain: x1, 10, 100.

Post-filter gain: x1, 2, 5, 10, 20, 50, 100, 200.

Gain accuracy: 1.5%
