Signal recovery 7265 dual phase lock in amplifier uses the latest digital signal processing dsp technology for measurement and control of experiments.
Sr810 dsp lock in amplifier manual.
10 m ω 25 pf ac or dc coupled.
The stanford research systems sr810 and sr830 are part of the srs family of dsp lock in amplifiers.
X r x noise aux input 1 or 2.
Y via interface only.
Full scale sensitivity 2 nv to 1 v in a 1 2 5 10 sequence expand off.
The sr810 lock in amplifier and sr830 lock in amplifier provide high performance at a reasonable cost.
Sr860 dsp lock in amplifier certification stanford research systems certifies that this product met its published specifications at the time of shipment.
Full scale sensitivity 2 nv to 1 v in a 1 2 5 10 sequence expand off.
Warranty this stanford research systems product is warranted against defects in materials and.
Current input 10 6 or 10 8 volts amp.
Both instruments use digital signal processing dsp to replace the demodulators output filters and amplifiers found in.
Sr830 dsp lock in amplifier 1 5 specifications signal channel voltage inputs single ended a or differential a b.
Sr810 dsp lock in amplifier specifications signal channel voltage inputs single ended a or differential a b.
Thus in the previous example with a 2 v pk pk.
1 k ω to virtual ground.
Y and q are available over the interface only offset x y and r may be offset up to 105 of full scale.
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.
Sr810 dsp lock in amplifier 1 6 displays channel 1 4 1 2 digit led display with 40 segment led bar graph.
Lock in amplifiers as a general rule display the input signal in volts rms.
The sr830 simultaneously displays the magnitude and phase of a signal while the sr810 displays magnitude only.
The display can also be any of these quantities divided by aux input 1 or 2.
When the sr830 dis plays a magnitude of 1v rms the component of the input signal at the reference frequency is a sine wave with an amplitude of 1 vrms or 2 8 v pk pk.
Sr810 and sr830 dsp lock in amplifiers signal to the full scale input voltage.
Current input or 10 volts amp.
