The model 7280 DSP Lock-in Amplifier 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 electroluminescent 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 numeric

keypad, while four cursor-movement keys

simplify use of the graphic display menus.

Users of the SIGNAL RECOVERY models

7260 and 7265 will find switching to the

7280 very easy, since we've designed it

with a similar menu structure. The only

significant changes are in some of the

control menus, where the better resolution

of the display allows both the controls and

the instrument outputs to be shown

simultaneously, for even faster feedback

on the effects of control adjustments.

Naturally, the instrument includes the extended operating modes like dual reference,

dual harmonic and virtual reference made popular by the 7260 and 7265, as well as the

spectral display mode used to aid reference frequency selection. It also includes GPIB

and RS232 interfaces for remote computer control and a range of auxiliary analog and

digital inputs and outputs. Compatible software is available in the form of a LabVIEW

driver supporting all instrument functions,

and the Acquire lock-in amplifier

applications software. The driver and a

free demonstration version of the

software, DemoAcquire, are available for

download from our website at

www.signalrecovery.com

In summary, if you need a lock-in capable

of working beyond the traditional audio

frequency band but still want the drift-free

performance that only digital demodulation

brings, then look no further - you have

found it in the SIGNAL RECOVERY Model

7280.
