Upgrade from pre 14.02 “Zurich Instruments HF2” LabVIEW Driver to “Zurich Instruments LabOne” LabVIEW Driver

on 2014-05-05 at 22:36 by Sadik
With release the 14.02 of the Zurich Instruments LabOne software, the LabVIEW driver was reworked so that it is compatible with all Zurich Instruments products. At the same time it was renamed from “Zurich Instruments HF2” to “Zurich Instruments LabOne”. […]

Sideband Analysis with Lock-in Amplifiers

on 2014-02-27 at 20:10 by Sadik
When a sinusoidal waveform is periodically modulated in either amplitude or frequency sidebands are generated as a result of this carrier modulation. These sidebands can be measured using a lock-in amplifier. Zurich Instruments lock-in amplifiers (HF2LI and UHFLI) can measure […]

Top 10 Ways to Improve Your Lock-in Amplifier Measurement

on 2013-11-08 at 10:55 by Sadik
Meanwhile I have helped so many people working with lock-in amplifiers with a handful of generally applicable Tricks, that I’d like to share them in a compact compilation. Certainly they apply to the Zurich Instruments HF2LI Lock-in Amplifier and to […]

Double-sideband Suppressed-carrier Modulation

on 2013-08-28 at 11:17 by Sadik
Double-sideband Suppressed-carrier (DSB-SC) modulation is an amplitude modulation, which consists only of the two symmetrical sidebands and no carrier band. I came across this scheme in an ultra-sound application, where the power utilization can be maximized when all power is […]

Broadcasting FM and AM Radio with the Zurich Instruments UHFLI 600 MHz Lock-in Amplifier

on 2013-05-06 at 17:19 by Sadik
Following my previous blog, Listening to FM Radio with the UHFLI 600 MHz Lock-in Amplifier and PLL, people advised me to also try and broadcast FM Radio. Naturally for this I had to retreat into Zurich Instruments’ shielded radiation lab, […]

Listening to FM Radio with the UHFLI 600 MHz Lock-in Amplifier and PLL

on 2013-04-17 at 11:10 by Sadik
A guy at Zurich Instruments soldered a 3.5mm headphone socket to a BNC cable and attached a 75-cm antenna wire to the Signal Input of our 600MHz UHFLI Lock-in Amplifier with UHF-PID PID/PLL option and was happily listening to FM […]
