863 Quad Filter Amplifier

 Specifications

PERFORMANCE

INPUT SIGNAL AMPLITUDE RANGE 0 to ±1.0 V ac signal; 0 to ±2 V dc offset; maximum input ±2 V signal plus offset.

OUTPUT AMPLITUDE RANGE 0 to ±5 V linear into a 50-W load. Output dc-coupled with dc offset <±10 mV.

RISE TIME <10 ns with Integration and Differentiation time constants set to Out, or »2.2t for other Integration settings and Differentiation Out.

CROSS TALK <0.01% from any output to any input measured at maximum gain with Integration and Differentiation time constants set to Out.

NOISE For maximum gain, rms noise referred to the input <50 µV with Integration and Differentiation set to Out; measured using a Hewlett-Packard 3400A true rms meter.

INTEGRAL NONLINEARITY <±0.5% over ±5 V into a 50-W load.

TEMPERATURE SENSITIVITY dc level <±10 µV/°C referred to the output. Gain sensitivity <±0.05%/°C.

OPERATING TEMPERATURE RANGE 0 to 50°C.

ELECTRICAL AND MECHANICAL

POWER The Model 863 unit does not have an internal power supply and must obtain power from a NIM-standard power supply such as the ORTEC Model 4001A/ 4002D NIM Bin/Power Supply.

POWER REQUIREMENTS +24 V, 83 mA; –24 V, 83 mA; +12 V, 167 mA; –12 V, 167 mA; +6 V, 320 mA; –6 V, 320 mA.

WEIGHT
Net 1.5 kg (3.3 lb).
Shipping 3.1 kg (7.0 lb).

DIMENSIONS NIM-standard single-width module 3.43 X 22.13 cm (1.35 X 8.714 in.) per DOE/ER-0457T.

CONTROLS

Each section of the Model 863 Quad Timing Filter Amplifier has separate controls for Coarse Gain, Fine Gain, P/Z, Differentiation, and Integration time constant.

COARSE GAIN PWB jumper selectable for nominally X1 or X5. The Model 863 is shipped with this jumper in the X5 position. Gain is reduced by a factor of 2 when using the cable clip.

FINE GAIN Front-panel screwdriver poten-tiometer continuously adjustable from nominally X2 to X50.

P/Z Front-panel screwdriver-adjustable potentiometer to adjust pole-zero cancellation for decay time constants from 25 µs to infinity.

DIFFERENTIATION Time constant PWB jumper selectable as either Out (equivalent to 0.1 ms) or 200 ns. A third position is available for custom modification. The Model 863 is shipped with this jumper in the Out position.

INTEGRATION Time constant PWB jumper selectable as either Out or 50 ns. A third position is available for custom modification. In the Out position, the 10% to 90% rise time is <10 ns. The Model 863 is shipped with this jumper in the Out position.

INVERT/NONINVERT PWB jumper selectable to Invert or Noninvert the Output signal relative to the Input signal. The Model 863 is shipped with this jumper in the Noninvert position.

INPUTS

INPUT Positive or negative polarity selectable with a PWB jumper; amplitude 0 to ±1 V ac signal; 0 to ±2 V dc offset; maximum input ±2 V signal plus offset. Input impedance is 100 W, protected to ±6 V. Front-panel LEMO connector.

CLIP Two front-panel LEMO connectors to provide delay line clipping of the input pulse using an external 50-W coaxial cable. Delay line clip is two times the cable propagation delay. Gain is reduced by a factor of two when using the cable clip.

OUTPUTS

OUTPUT Front-panel LEMO connector furnishes the shaped and amplified signal through Z_o <1 W; amplitude to ±5 V, rise time and decay time controlled by the Integration and Differentiation time constant settings. Output is dc-coupled and controlled by a continuous baseline restorer.
