Sr860 500 khz dsp lock in amplifier.
Sr810 dsp lock in amplifier manual.
Sr810 and sr830 dsp lock in amplifiers signal to the full scale input voltage.
Both instruments use digital signal processing dsp to replace the demodulators output filters and amplifiers found in.
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.
Current input 10 6 or 10 8 volts amp.
Voltage current sources.
Fft spectrum analyzers.
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.
Y via interface only.
Lock in amplifiers as a general rule display the input signal in volts rms.
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.
10 m ω 25 pf ac or dc coupled.
1 k ω to virtual ground.
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.
Sr860 dsp lock in amplifier certification stanford research systems certifies that this product met its published specifications at the time of shipment.
Signal recovery 7265 dual phase lock in amplifier uses the latest digital signal processing dsp technology for measurement and control of experiments.
Sr830 dsp lock in amplifier 1 5 specifications signal channel voltage inputs single ended a or differential a b.
The sr830 simultaneously displays the magnitude and phase of a signal while the sr810 displays magnitude only.
Using dsp technology pioneered by srs these units deliver unmatched digital performance at a price below that of most conventional lock in amplifiers.
Y and q are available over the interface only offset x y and r may be offset up to 105 of full scale.
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.
The stanford research systems sr810 and sr830 are part of the srs family of dsp lock in amplifiers.
The display can also be any of these quantities divided by aux input 1 or 2.
