Signal Recovery 7280 Lock-in Amplifier 0.5 Hz - 2 MHz

The Signal Recovery 7280 Lock-in Amplifier 0.5 Hz - 2 MHz is an exceptionally versatile instrument with outstanding performance. With direct digital demodulation over an operating frequency extending up to 2.0 MHz, output filter time constants down to 1 µs and a main ADC sampling rate of 7.5 MHz it is ideal for recovering fast changing signals. But unlike some other high frequency lock-ins, it also works in the traditional audio frequency band.

In addition to its excellent technical specifications, it is also very easy to use. The front panel is dominated by a large electro-luminescent display panel, used both to show the instrument's outputs and for adjusting its controls via a series of menus. Controls are set by a combination of the use of the keys surrounding the display and the keypad, while four cursor-movement keys simplify use of the graphic display menus.
