Reduce Ground Disturbances when using HF2TA Transimpedance Amplifier in a Measurement Setup

on 26.02.2014 at 18:13 by James Wei
Ground loops can potentially pose a serious problem in many measurement setups. Due to the multiple connections to and from the HF2TA current amplifier and other external components, several ground loop related issues can pop up in the signal being […]

Using HF2IS Impedance Spectroscope for FRA, 2-Terminal and 4-Terminal Measurements

on 19.09.2013 at 14:14 by James Wei
Often there are questions from our HF2IS Impedance Spectroscope users on how to configure the HF2IS for frequency response analysis (FRA), 2-Terminal impedance measurement, or 4-Terminal impedance measurement. This short blog will clarify the proper physical connections as well as […]

Remote Access to HF2 Instruments on the LAN

on 07.06.2013 at 08:56 by James Wei
As explained in the HF2 User Manual, users can configure in ziControl to connect to any ziServer host on the LAN i.e. remote client access to HF2 Instrument. This blog will sum up an easy two-steps procedure to do exactly […]

Optimize Your HF2TA Transimpedance Amplifier Settings

on 24.05.2013 at 11:43 by James Wei
Users of the HF2TA transimpedance amplifier should always be aware of the trade-off between the transimpedance gain and the 3-dB roll-off bandwidth of the amplifier. (Hint: Since the HF2 software release 12.08, the bandwidth is also specified in the HF2TA […]

Optimize Your Frequency Sweep for Static Impedance Measurement

on 28.02.2013 at 08:20 by James Wei
Very often people want to measure very large static impedance (e.g. small capacitance, large resistance) over a wide frequency range. In the very low frequency region, one may notice that measured curve is not smooth but rather “jiggly”, just like […]
