Product Specifications
Amplifier Analog Output Amplifier
±10 Volts at 100 mA. Output current limited to 150 mA. No instability with capacitive loads to 1 µF. Less than 0.1 Ohm in series with 5 µH. Each output may be configured by jumper for wideband or filtered response.
Amplifier Bandwidth
100 kHz (-3 dB) for all gains 1 to 1,000. Bandwidth is reduced in proportion to gain above 1,000.
Amplifier Cm Voltage
Common Mode ±300V DC or peak AC operating.
Amplifier Common Mode
130 dB at DC, 123 dB at 60 Hz for gain 1,000, and 1 K Ohm source unbalance. At lower gains common mode rejection is 63 dB plus gain in dB. CMR decreases at a rate not exceeding 6 dB/octave from value at 60 Hz.
Amplifier Gain
Eleven steps: 1, 2, 5, 10, 20, 50, 100, 200, 500, 1,000 and 2,000.
Amplifier Gain Accuracy
±0.1%. ±0.02% with Option P input attenuator.
Amplifier Gain Linearity
±0.01 %
Amplifier Gain Stability
±0.01% for 6 months, ±0.002%/ºC for fixed gain steps.
Amplifier Input Impedance
50 Megohms shunted by 200 pF.
Amplifier Input Protection
Will withstand differential input of ±50 Volts and common mode voltage of ±350 Volts.
Amplifier Noise 100 Khz
7 µV RTI plus 0.6 mV RTO, RMS.
Amplifier Noise 10 Hz
1 µV RTI plus 0.5 mV RTO, peak.
Amplifier Noise 10 Khz
3 µV RTI plus 0.3 mV RTO, RMS.
Amplifier Overload Recovery
Recovers from 5 times full scale overload to within ±0.1% in less than 400 µS at gain 1000, and faster at lower gains.
Amplifier Setting Time
75 µS to within ±0.1% final value.
Amplifier Slew Rate
3.1 V/µS RTO, 1.5 V/µS RTI.
Amplifier Source Current
±1 nA, ±0.5 nA/ºC.
Amplifier Source Impedance
1,000 Ohms in any unbalance. Input may be grounded or floating.
Amplifier Variable Gain
Screwdriver adjustable gain multiplier increases the gain to cover the range between steps. Switch selects variable or calibrated gain. RTO errors and noise are multiplied by variable gain setting.
Amplifier Zero
Front panel controls provide independent adjustment of input and output zero.
Amplifier Zero Stability
±5 µV RTI, ±0.5 mV RTO. Temperature coefficient is ±0.4 µV/ºC RTI, ±0.15 mV/ºC RTO.
Calibration Voltage Substitution
Voltage Substitution Amplifier input is switched to a voltage calibration bus for application of externally supplied calibration signal. Activated individually for each channel by a control input. Connecting the control input to output common selects calibration.
Filter Filter 70a 5
Switch selectable, 12 dB/octave Bessel low pass with 3 dB bandwidth steps of 1 Hz, 10 Hz, 100 Hz, 1 kHz, 10 kHz and Wideband.
Filter Filter 70a 6
Switch selectable, 36 dB/octave Bessel low pass with 3 dB bandwidth steps of 1 Hz, 10 Hz, 100 Hz, 1 kHz, 10 kHz and Wideband.
Filter Other
