STANFORD RESEARCH SYSTEMS SR830 DSP Lock-In Amplifier

The Stanford Research SR830 DSP Lock-In Amplifier is used to detect and measure very small AC signals - all the way down to a few nanovolts. Accurate measurements may be made even when the small signal is obscured by noise sources many thousands of times larger. Specifications. SIGNAL CHANNEL; Voltage Inputs: Single-ended (A) or differential (A-B). Current Input: 106 or 108 Volts/Amp. Full Scale Sensitivity: 2 nV to 1 V in a 1-2-5-10 sequence (expand off). Input Impedance Voltage: 10 M-ohm +25 pF, AC or DC coupled. Input Impedance Current: 1 k-ohm to virtual ground. Gain Accuracy: ±1% from 20°C to 30°C (notch filters off), ±0.2 % Typical. Input Noise: 6 nV/sqrt Hz at 1 kHz (typical). Signal Filters: 60 (50) Hz and 120(100) Hz notch filters (Q=4). CMRR: 100 dB to10 kHz (DC Coupled), decreasing by 6db/octave above 10 kHz. REFERENCE CHANNEL; Frequency Range: 1 mHz to 102 kHz. Reference Input: TTL (rising or falling edge) or Sine, Sine input is1 M-ohm, AC coupled (>1 Hz). 400 mV pk-pk minimum signal. Phase Resolution: 0.01°. Absolute Phase Error: <1°. Relative Phase Error: <0.01°. Orthogonality: 90° ± 0.001°. Phase Noise: External synthesized reference: 0.005° rms at 1 kHz, 100 ms, 12 dB/oct. Internal reference: crystal synthesized, <0.0001° rms at 1 kHz. DEMODULATOR; Zero Stability: Digital displays have no zero drift on all dynamic reserves, Analog outputs: <5 ppm/°C for all dynamic reserves. Time Constants: 10 µs to 30 s (reference > 200 Hz). 6, 12, 18, 24 dB/oct rolloff, up to 30000 s (reference < 200 Hz). 6, 12, 18, 24 dB/oct rolloff, Synchronous filtering available below 200 Hz. Harmonic Rejection: -80 dB. INTERNAL OSCILLATOR; Frequency: 1 mHz to 102 kHz. Frequency Accuracy: 25 ppm + 30 µHz. Frequency Resolution: 4 1/2 digits or 0.1 mHz, whichever is greater. Distortion f<10 kHz, below -80 dBc. f>10 kHz, below -70 dBc.1 Vrms amplitude. Output Impedance: 50 ohm. Amplitude: 4 mVrms to 5 Vrms (into a high impedance load) with 2 mV resolution, (2 mVrms to 2.5 Vrms into 50 ohm load). Amplitude Accuracy: 1%. Amplitude Stability: 50 ppm/°C. Outputs: Sine output on front pane, TTL sync output on rear panel, When using an external reference, both outputs are phase locked to the external reference. DISPLAYS; Channel 1 and Channel 2: 4 1/2 digit LED display with 40 segment LED bar graph. Interfaces: IEEE-488 and RS232 interfaces standard.

*This is a Web introductory price for one calibration of the STANFORD RESEARCH SYSTEMS SR830. Price does not in most cases include measurement performance data. Pricing does include NIST traceable calibration and issue of a calibration certificate and calibration label. Pricing may vary slightly due to volume and location of laboratory supporting calibration. Volume pricing may apply. On-site fees may apply depending on logistics, location and volume of work to be completed during the visit.

Adjacent Channel Power
Adjacent Channel Power is the power from a modulated communications channel that leaks into an adjacent channel. This leakage is usually specified as a ratio to the power in the main channel, but is sometimes an absolute power.

Fall Time
Fall time is the time required for the amplitude of a pulse to decrease (fall) from a specified value (usually 90 percent of the peak value exclusive of overshoot or undershoot) to another specified value (usually 10 percent of the maximum value exclusive of overshoot or undershoot).

Overshoot
Overshoot is the distortion that follows a major transition; the difference between the peak power point and the pulse-top amplitude computed as a percentage of the pulse-top amplitude.
