Sr810 dsp lock in amplifier manual.

Warranty this stanford research systems product is warranted against defects in materials and. The sr810 lock in amplifier and sr830 lock in amplifier provide high performance at a reasonable cost. The display can also be any of these quantities divided by aux input 1 or 2. Full scale sensitivity 2 nv to 1 v in a 1 2 5 10 sequence expand off.

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. The sr830 simultaneously displays the magnitude and phase of a signal while the sr810 displays magnitude only. Sr810 dsp lock in amplifier 1 6 displays channel 1 4 1 2 digit led display with 40 segment led bar graph. Y via interface only.

Thus in the previous example with a 2 v pk pk. Y and q are available over the interface only offset x y and r may be offset up to 105 of full scale. Fft spectrum analyzers. Sr810 dsp lock in amplifier specifications signal channel voltage inputs single ended a or differential a b.

Sr830 dsp lock in amplifier 1 5 specifications signal channel voltage inputs single ended a or differential a b. Lock in amplifiers as a general rule display the input signal in volts rms. Signal recovery 7265 dual phase lock in amplifier uses the latest digital signal processing dsp technology for measurement and control of experiments. The stanford research systems sr810 and sr830 are part of the srs family of dsp lock in amplifiers.

Voltage current sources. Current input or 10 volts amp. Sr810 and sr830 dsp lock in amplifiers signal to the full scale input voltage. Current input 10 6 or 10 8 volts amp.

Full scale sensitivity 2 nv to 1 v in a 1 2 5 10 sequence expand off. 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. X r x noise aux input 1 or 2. Sr860 dsp lock in amplifier certification stanford research systems certifies that this product met its published specifications at the time of shipment.
