The sr810 lock in amplifier and sr830 lock in amplifier are simple to use.

In this video i am talking about sr830 lock in amplifier which includes its principle and working. All instrument functions are set from the front panel keypad and a spin knob is provided to quickly adjust parameters. A lock in amplifier can make accurate measurements of small signals even when the signals are obscured by noise sources which may be a thousand times larger. Sr810 dsp lock in amplifier specifications signal channel voltage inputs single ended a or differential a b.

The display can also be any of these quantities divided by aux input 1 or 2. The instrument utilizes digital signal processing dsp to replace the demodulators output filters and amplifiers found in conventional lock ins. Full scale sensitivity 2 nv to 1 v in a 1 2 5 10 sequence expand off. The heart of the sr810 and sr830 like any lock in amplifier is the demodulator which multiplies the input signal by the reference signal and filters the result.

X r x noise aux input 1 or 2. The sr830 dsp lock in amplifier provides high performance at a reasonable cost. The sr830 simultaneously displays the magnitude and phase of a signal. The demodulator of the sr810 and sr830 is a dsp processor capable of performing 16 million 24 bit multiplications and additions every second.

When the sr830 dis plays a magnitude of 1v rms the component of. Only inputs at frequencies at the reference frequency result in an output. Y via interface only. The sr810 lock in digital amplifier lida provides high performance at a reasonable cost.

Essentially a lock in is a filter with an arbitrarily narrow bandwidth which is tuned to the frequency of the signal. Y and q are available over the interface only offset x y and r may be offset up to 105 of full scale.
