4 1/2 digit LED display with 40 segment LED bar graph.
X, R, X Noise, Aux Input 1 or 2. The display can also be any of these
quantities divided by Aux Input 1 or 2.
(Y and q are available over the interface only.)
X, Y and R may be offset up to ±105% of full scale. (Y via interface only)
X, Y and R may be expanded by 10 or 100. (Y via interface only)
4 1/2 digit LED display.
Display and modify reference frequency or phase, sine output amplitude,
harmonic detect, offset percentage (Xor R), or Aux Outputs 1-4.
8k points from Channel 1 display may be stored internally. The internal data
sample rate ranges from 512 Hz down to 1 point every 16 seconds. Samples
can also be externally triggered. The data buffer is accessible only over the
computer interface.
Output proportional to Channel 1 display, or X.
Output Voltage: ±10 V full scale. 10 mA max output current.
Rear panel outputs of cosine (X) and sine (Y) components.
Output Voltage: ±10 V full scale. 10 mA max output current.
4 BNC Digital to Analog outputs.
±10.5 V full scale, 1 mV resolution. 10 mA max output current.
4 BNC Analog to Digital inputs.
Differential inputs with1 MΩ input impedance on both shield and center
conductor. ±10.5 V full scale, 1 mV resolution.
TTL trigger input triggers stored data samples.
Analog output of signal amplifiers (before the demodulator).
IEEE-488 and RS-232 interfaces standard.
All instrument functions can be controlled through the IEEE-488 and RS-232
interfaces.
Power connector for SR550 and SR552 preamplifiers.
40 Watts, 100/120/220/240 VAC, 50/60 Hz.
17"W x 5.25"H x 19.5"D
