Compensating Cables for Accurate Impedance Measurements

on 19.01.2021 at 10:45 by Tim Ashworth on Blog of Tim Ashworth
Measuring impedance accurately can be a challenge, especially when the device or material under test is located some distance away from the impedance analyzer at the end of cables. The phase delay and parasitic impedance of the cables can significantly […]

Webinar Summary – Boost Your SPM Applications: From Kelvin Probe to Time-Resolved Measurements

on 19.10.2020 at 17:03 by Romain Stomp on Blog of Romain Stomp
Following up on the webinar dedicated to Kelvin Probe Force Microscopy (KPFM) techniques, I’d like to post a short summary in this blog as well as answers to most questions raised during this event. The recording of this webinar can […]

Webinar Q&A- Impedance Analysis; Measuring Fast and Low

on 23.06.2020 at 08:01 by Tim Ashworth on Blog of Tim Ashworth
This blog post answers the many welcome questions from the audience during the recent webinar “Impedance Analysis; Measuring Fast and Low”. This webinar covered two distinct and equally important impedance measurement challenges. The first involves measuring the low equivalent series […]

Sensor Characterization and Control

on 25.05.2020 at 08:00 by kivanc on Blog of Kivanç Esat
Sensors come with different flavors. They can be inertial devices for motion detection; can be based on photosensitive materials; can be absorbing surrounding molecules to detect their concentration, and so on. Developments in micromachining and micro/nanoelectromechanical system (MEMS/NEMS) technologies lead to miniaturization and low power consumption. Hence, multiple sensors […]

How to reduce noise floor and improve SNR by employing cross-correlation techniques

on 19.05.2020 at 15:30 by Jithesh Srinivas on Blog of Jithesh Srinivas
Ultra-sensitive voltage measurements is a crucial requirement for applications such as quantum device characterization [1]. Weak signals become easily obscured by thermal noise, especially that coming from the measurement apparatus; this increases the noise floor [2] and determines a lower […]

Choose the right tool to acquire Lock-in data

on 20.02.2020 at 10:03 by kivanc on Blog of Kivanç Esat
A crucial part of setting up an experiment is to integrate proper instrumentation to collect and save data. It is important not only to have correct results but also to ensure an efficient workflow. This blog post and related video […]

DC I-V Sweeps on the MFIA

on 10.01.2020 at 09:07 by Tim Ashworth on Blog of Tim Ashworth
Characterizing the impedance of components and materials with the MFIA is done by necessity with an AC signal. However, the MFIA and MFLI can also take DC measurements. This blog post shows how easy it is to take DC measurements, […]

Reloading Data into LabOne Modules

on 29.08.2019 at 12:48 by Tim Ashworth on Blog of Tim Ashworth
LabOne now supports reloading data into the LabOne Modules when using the HDF5 file format. Starting from LabOne 19.05, data acquired in modules such as the Sweeper, DAQ, Scope and Spectrum Analyzer, can now be reloaded into the same LabOne […]

Connect MFLI with External Signal Generator

on 26.07.2019 at 16:18 by Marco Brunner on Blog of Marco Brunner
This blog describes how to use an MFLI lock-in amplifier with an external reference frequency. The reference frequency comes from a signal generator Model 6221 from Keithley which is used to apply higher voltage pulses or sinusoidal signals on the […]

Protect Setup From High Voltage Peaks

on 24.11.2017 at 11:24 by Marco Brunner on Blog of Marco Brunner
This blog describes how a setup can be protected from overvoltage which occurs switching off a coil. Fast changing currents induce transient voltages in an inductive load which can be expressed by the formula: V = – L (dI/dt) L is […]

Output Low-Frequency Sinusoidal Signal on the AUX Output of MFLI

on 30.05.2017 at 14:42 by Marco Brunner on Blog of Marco Brunner
  This blog shows how to output sinusoidal signals on the AUX Output with the MD multi-demodulator option. Keep in mind that the AUX output are not designed to output sinusoidal signals as the Signal Output.   Setup 1. On AUX […]

Fast auto-approach with MFLI Threshold Unit to control stepper motor

on 22.02.2017 at 11:19 by Romain Stomp on Blog of Romain Stomp
In many applications where the distance between two objects need to be reduced to a predefined gap, the ability to control a stepper motor with clear stop conditions from different sensors is of high practical interest. Such functionality can be […]

Compensating delay-induced phase shifts for high-frequency resonators

on 20.02.2017 at 14:31 by Romain Stomp on Blog of Romain Stomp
Phase-Locked Loop (PLL) or other PID controllers on nano-mechanical resonators rely on clean phase signals that exhibit large slope, or significant phase shift, around the resonance frequency. For really high-frequency NEMS and opto-mechanical systems above a few tens or hundreds […]

LabOne for HF2: using digital lines as trigger sources

on 03.02.2016 at 11:39 by Romain Stomp on Blog of Romain Stomp
Since LabOne 15.11 release and onward, accessible from our download area, all HF2LI users with the enabled HF2LI-WEB option can now benefit from the latest software developments that were previously reserved for the UHFLI. One tool that is now totally new for this […]

LabOne Software Trigger as a tool for multichannel mapping applications

on 25.11.2015 at 13:27 by Romain Stomp on Blog of Romain Stomp
In earlier blogs, we presented several methods to synchronize data acquisition with third party instruments, either via the DIO input as a Hardware trigger (TTL pulse), some gated triggering scheme for pass/fail analysis or to capture only transient phenomena in a longer […]
