SR830 DSP Lock-In Amplifier
1-6
DISPLAYS
Channel 1 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.
Channel 2 4 1/2 digit LED display with 40 segment LED bar graph.
Y,
θ
, Y Noise, Aux Input 3 or 4. The display can also be any of these
quantities divided by Aux Input 3 or 4.
Offset X, Y and R may be offset up to ±105% of full scale.
Expand X, Y and R may be expanded by 10 or 100.
Reference 4 1/2 digit LED display.
Display and modify reference frequency or phase, sine output amplitude,
harmonic detect, offset percentage (X, Y or R), or Aux Outputs 1-4.
Data Buffer 16k points from both Channel 1 and Channel 2 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.
