The AR3030 offers the very latest technology through use of its’ DDS (Direct Digital Synthesizer). The legendary Collins 6kHz AM filter is fitted as standard to provide the highest levels of AM selectivity. High stability is accomplished by the standard fitting of a TCXO (Temperature Compensated Crystal Oscillator). As the model name would suggest, the tunable coverage is 30kHz - 30 MHz (with 29.999995 MHz being the actual upper limit of tuning) using silky-smooth 5Hz steps. The A ...

INTRODUCTION The Model 128A Lock-In Amplifier enables the accurate measurement of signals contaminated by broad band noise, power line pickup, frequency drift, or other sources of interference. It does this by means of an extremely narrow band detector which has the center of its passband locked to the frequency of the signal to be measured. Because of the frequency lock and narrow bandwidth, large improvements in signal-to-noise ratio can be achieved, allowing the signal of interest ...
