The sr810 lock in amplifier and sr830 lock in amplifier provide high performance at a reasonable cost.
Sr810 dsp lock in amplifier manual.
Both instruments use digital signal processing dsp to replace the demodulators output filters and amplifiers found in.
Current input 10 6 or 10 8 volts amp.
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.
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.
Fft spectrum analyzers.
The sr830 simultaneously displays the magnitude and phase of a signal while the sr810 displays magnitude only.
Sr830 dsp lock in amplifier 1 5 specifications signal channel voltage inputs single ended a or differential a b.
1 k ω to virtual ground.
Full scale sensitivity 2 nv to 1 v in a 1 2 5 10 sequence expand off.
The display can also be any of these quantities divided by aux input 1 or 2.
Lock in amplifiers as a general rule display the input signal in volts rms.
Y and q are available over the interface only offset x y and r may be offset up to 105 of full scale.
X r x noise aux input 1 or 2.
