SR560 Specifications
Input
Inputs AC or DC coupled, single-ended
or differential
Input impedance 100 MΩ + 25 pF
Maximum input 3 Vpp
CMRR 100 dB from DC to 1 kHz
(100 mV common mode input at
1 kHz, gain of 100, low noise mode.
Decreases by 6 dB/octave from
1 kHz to 1 MHz)
Noise 4 nV/√Hz at 1 kHz
Gain 1 to 50,000 in 1-2-5 sequence
Vernier gain in 0.5 % steps
Gain stability 200 ppm/°C
Bandwidth –3 dB at 1.2 MHz (typ.)
Flatness ±0.3 dB to 300 kHz
(gains up to 1000)
Filters
Signal filters 2 configurable (low-pass or high-
pass) 6 dB/oct rolloff filters.
–3 dB points are settable in a 1-3-10
sequence from 0.03 Hz to 1 MHz.
Gain allocation High Dynamic Reserve — Gain is
increased after the signal filters to
prevent overloading.
Low Noise — Gain is increased
before the filters to improve
noise figure.
Output
Maximum output 10 Vpp into 50 Ω and 600 Ω
Filter reset Long time constant filters may be
reset with front-panel button.
DC drift 5 µV/°C referred to input
(DC coupled)
Distortion 0.01 % at 1 kHz
Rear panel ±12 VDC @ 200 mA referenced to
amplifier ground
General
External gating TTL input sets gain to zero
Interfaces RS-232, 9600 baud, receive only
Power 100/120/220/240 VAC, 6 W charged,
30 W while charging. Internal batteries
provide 15 hours of operation between
charges. Batteries are charged while
connected to the line.
