Stanford SR860 Lock-In放大器 (0.001 Hz - 500 kHz)

Signal Channel:

Voltage inputs:  Single-ended (A) or differential (A-B)

Sensitivity/Output Scale:

1 nV to 1 V (voltage input),

1 fA to 1 µA (current input)

Voltage Input range: 10 mV to 1 V (peak)

Current input range: 1 µA or 10 nA (peak)

Max input before overload: 1 V (peak) or 1 µA (peak)

Input impedance:

Voltage input: 10 MΩ + 25 pF, AC (>1 Hz) or DC coupled

Current input: 1 kΩ or 100 Ω to virtual ground

Gain accuracy: ±1 % (<200 kHz), ±2 % (to 500 kHz). Signal amplitude must be less than 30 % of input range.

Noise: 2.5 nV/√Hz at 1 kHz (10 mV input range, typ.)

Reference Channel:

Frequency range: 0.001 Hz to 500 kHz

Timebase: 10 MHz In/Out (phase locks the internal frequency to other SR860s.)

Input impedance: 1 MΩ or 50 Ω

Phase setting resolution: (360/232) degrees

Phase noise:

Int. reference: <0.0001° rms at 1 kHz (100 ms, 12 dB/oct)

Ext. reference: (typ) <0.001° rms at 1 kHz (100 ms, 12 dB/oct)

Demodulator:

DC stability: Digital output values have no offset drift

Time constants: 1 µs to 30 ks

Low pass filters: Typical RC-type filters or advanced Gaussian/Phase-Linear filters

Filter slope: 6, 12, 18 or 24 dB/oct rolloff

Internal Oscillator:

Frequency: 1 mHz to 500 kHz

Frequency accuracy: 25 ppm + 30 µHz (with internal timebase)

External timebase: 10 MHz timebase input/output on rear panel

Frequency resolution: 6 digits or 0.1 mHz (whichever is greater)

Sine Output:

Outputs: Differential or single-ended

Output impedance: 50 Ω source

Amplitude resolution: 3 digits or 1 nV, whichever is greater

DC offset: ±5 V, differential or common mode

Offset resolution: 3 digits or 0.1 mV, whichever is greater

Output limit: ±6 V, sum of DC offset and peak amplitude

Data:

Data channels: 4 data channels are displayed and graphed (green, blue, yellow, orange)

Data sources: Each data channel can be assigned any of these data sources: X, Y, R, Θ, Aux In 1 to 4, Aux Out 1 to 2, X noise, Y noise, Sine Out Amplitude, Sine Out DC Level, Reference Phase, or Reference Frequency

Inputs and Outputs:

CH1 output: Proportional to X or R, ±10 V full scale thru 50 Ω

CH2 output: Proportional to Y or Θ, ±10 V full scale thru 50 Ω

X and Y rear-panel outputs: Proportional to X and Y, ±10 V full scale thru 50 Ω

General:

Interfaces: IEEE488.2, RS-232, USB device and Ethernet.

USB flash: Front-panel slot for USB flash storage of screen shots and data

Preamp power: 9-pin D connector to power SRS preamps

Power: 60 W, 100/120/220/240 VAC, 50/60 Hz

Dimensions: 17" × 5.25" × 17" (WHL)

Weight: 22 lbs.
