Sr810 Dsp Lock In Amplifier Manual

10 m ω 25 pf ac or dc coupled.

Sr810 dsp lock in amplifier manual. Sr810 dsp lock in amplifier specifications signal channel voltage inputs single ended a or differential a b. The largest interfering signal is defined as the amplitude of the largest signal at any frequency that can be applied to the input before the lock in cannot measure a signal with its specified accuracy. 1 k ω to virtual ground. The stanford research systems sr810 and sr830 are part of the srs family of dsp lock in amplifiers.

Current input 10 6 or 10 8 volts amp. Current input or 10 volts amp. The sr830 simultaneously displays the magnitude and phase of a signal while the sr810 displays magnitude only. Y and q are available over the interface only offset x y and r may be offset up to 105 of full scale.

Both instruments use digital signal processing dsp to replace the demodulators output filters and amplifiers found in. Lock in amplifiers as a general rule display the input signal in volts rms. Sr810 dsp lock in amplifier 1 6 displays channel 1 4 1 2 digit led display with 40 segment led bar graph. The sr810 lock in amplifier and sr830 lock in amplifier provide high performance at a reasonable cost.

Sr810 and sr830 dsp lock in amplifiers signal to the full scale input voltage. Sr830 dsp lock in amplifier 1 5 specifications signal channel voltage inputs single ended a or differential a b. Sr860 500 khz dsp lock in amplifier. X r x noise aux input 1 or 2.

Thus in the previous example with a 2 v pk pk. Signal recovery 7265 dual phase lock in amplifier uses the latest digital signal processing dsp technology for measurement and control of experiments. Using dsp technology pioneered by srs these units deliver unmatched digital performance at a price below that of most conventional lock in amplifiers. Y via interface only.

Fft spectrum analyzers. The display can also be any of these quantities divided by aux input 1 or 2. Voltage current sources. Warranty this stanford research systems product is warranted against defects in materials and.

Full scale sensitivity 2 nv to 1 v in a 1 2 5 10 sequence expand off.
