Digital Lockin Amplifiers
Scitec Instruments has recently introduced the
Model 450DV2 multichannel digital lock-in amplifier
which enables simultaneous processing of up to 16 signals. It can extract and
measure up to 16 different signals in parallel from either of two analogue
inputs. This enables multiple harmonic or subharmonics to be monitored and
measured simultaneously, without the need to repeat experiments. Also unique to
the 450DV2 is the option to perform sum and difference measurements of two
reference frequencies and to perform offset frequency measurements.
Scitec Instruments' DSP lock-in amplifier,
Model 450s, is also available. The technology is also
available in house for custom digital lock-in amplifier designs. A complete
instrument that includes an integrated digital lock-in amplifier has already
been successfully designed for a customer. The lock-in amplifier design
performed as well as that of an instrument costing x100 more, although the
frequency range is limited. An alternative architecture allows single channel
operation at up to 10 MHz, 10 channels at 1 MHz or 100 channels at 100 kHz.
If you have a design that includes a digital lock-in
but is not practical due to cost or if you have a requirement for multiple
channels then please contact us with your
requirements.
Details of a custom digital lock-in produced already
are given on our specials page.
