SPECIFICATIONS
All specifications are with no load unless otherwise noted.
OUTPUT
Output Voltage Range
0 to +1.5 kV DC or peak AC, or
0 to -1.5 kV DC or peak AC, or
0 to ±750 V DC or peak AC
(jumper pin programmable).
Output Current Range
0 to ±50 mA DC, continuous
(100 mA peak for 10 µs).
AMPLIFIER INPUT
Input Voltage Range
0 to ±10 V DC or peak AC.
Input Impedance (Noninverting)
100 kΩ, nominal.
FEATURES
The Model 50/750 consists of a power supply module
with up to two modular amplifier channels which can
be mounted together in a half rack enclosure.
Digital Enable (Power Supply Module)
An input providing a connection for a TTL
compatible signal to turn on and off the high-
voltage output. A TTL low turns on the high-
voltage output. A TTL high turns off the high-
voltage output.
Gain Control
The DC gain of the Model 50/750 can be adjusted
using a potentiometer from 15 to 300 V/V.
Dynamic Adjustment
Two graduated potentiometers are used to
optimize the damping and response of the output
signal.
Zero Adjustment
A multi-turn potentiometer can adjust for zero volt
output when a zero volt input is applied.
PERFORMANCE
DC Voltage Gain
15 to 300 V/V, adjustable.
DC Voltage Gain Accuracy
Better than 0.1% of full scale.
Offset Voltage
Less than ±500 mV.
Output Noise
0 to +1500 V range or
0 to -1500 V range
Less than 50 mV rms to 20 kHz for a 1 nF
load (measured with the true rms feature of
the Hewlett Packard Model 34401A digital
multimeter).
0 to ±750 V range
Less than 60 mV rms to 20 kHz for a 1 nF
load (measured with the true rms feature of
the Hewlett Packard Model 34401A digital
multimeter).
Slew Rate (10% to 90%)
Greater than 125 V/µs.
Large Signal Bandwidth (1% distortion)
DC to greater than 8 kHz.
Small Signal Bandwidth (-3 dB)
DC to greater than 30 kHz.
Settling Time to 1%
Less than 50 µs when critically damped.
Stability
Drift with Temperature
Less than 50 ppm/°C.
Drift with Time
Less than 10 ppm/hr, noncumulative.
