Lock in amplifiers as a general rule display the input signal in volts rms.
Sr810 lock in amplifier manual.
Full scale sensitivity 2 nv to 1 v in a 1 2 5 10 sequence expand off.
X r x noise aux input 1 or 2.
Essentially a lock in is a filter with an arbitrarily narrow bandwidth which is tuned to the frequency of the signal.

Sr810 dsp lock in amplifier specifications signal channel voltage inputs single ended a or differential a b.
In this video i am talking about sr830 lock in amplifier which includes its principle and working.
Y via interface only.
The display can also be any of these quantities divided by aux input 1 or 2.
The primary advantage that a lock in amplifier pro vides.
Y and q are available over the interface only offset x y and r may be offset up to 105 of full scale.
Simultaneously displays the magnitude and uses digital signal processing dsp to replace the demodulators output filters and amplifiers found in conventional lock ins.
The sr830 simultaneously displays the magnitude and phase of a signal.
All instrument functions are set from the front panel keypad and a spin knob is provided to quickly adjust parameters.
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.
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.
The instrument utilizes digital signal processing dsp to replace the demodulators output filters and amplifiers found in conventional lock ins.
Up to nine different instrument configurations can be stored in non volatile ram for fast and easy instrument setup.
Sr810 dsp lock in amplifier 1 6 displays channel 1 4 1 2 digit led display with 40 segment led bar graph.
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.
The sr810 lock in digital amplifier lida provides high performance at a reasonable cost.
