Software & Automation

Gain/Phase Mode
The Gain/Phase Mode supports measuring the gain and phase shift of electronic circuits at one specific frequency. You can choose your results to be shown either in Cartesian or Polar coordinates.

Impedance/Reflection Mode
The Impedance/Reflection mode is designed to measure complex impedance and reflection at one specific frequency. It calculates the series and the parallel equivalent circuits to display them graphically. You can choose your results to be shown either in Cartesian or Polar coordinates.

Frequency Sweep Mode
The Frequency Sweep Mode supports a great variety of frequency sweep measurements. To characterize any device under test completely, you can perform linear and logarithmic sweeps. Impedance, Reflection, Admittance, Group Delay, Gain and Phase can be measured from 1Hz to 50MHz.
Various different diagrams help you to examine the tested circuit: For the in-depth analysis the Bode Analyzer Suite offers Polar, Nyquist, Smith and Cartesian diagrams. The latter are available with linear and logarithmic axis scaling. Cursors help you to find resonance frequencies or zero crossings in the measured curves.

Frequency Sweep Mode - External Coupler
This mode was especially designed to perform impedance or reflection measurements with external couplers or impedance measurement bridges. It offers you the same functionality as the Frequency Sweep mode.

Frequency Sweep Mode - Impedance Adapter
This mode makes your measurements easier, if you want to measure the impedance of electronic components using our impedance adapters. Ideally, you use your Bode 100 with the B-WIC or the B-SMC.

Device Configuration
Set up the Bode 100 according to your needs! The Device configuration helps you to configure the device hardware correctly. You can switch the input impedance from 50 Ohm to 1MOhm and connect the reference signal either internally or externally.

Reporting and Documentation
With the Bode Analyzer Suite it is easy for you to create a one-click report on your measurement, including all relevant device settings and measurement curves.
You can also copy and paste the diagrams directly into a word processor like Microsoft Office Word. Furthermore all measurement values can be exported to a comma-separated value file for further processing in any spreadsheet application or math program.

Note: You can save every measurement to a *.bode file. It contains all measurement data and device settings for archiving and/or sharing measurements. Bode-files can be analyzed with the Bode Analyzer Suite even if no Bode 100 hardware is connected.

Cursors and Cursor Grid
The cursor grid shows cursor values and special calculation results. Use the cursors to find minima and maxima in the curves or any specific values.

Probe and User Calibration
You want to compensate the cables or the measurement setup? The Bode Analyzer Suite offers THRU calibration for the Gain/Phase measurements and OPEN SHORT LOAD calibration for impedance/reflection measurements. You can apply all necessary settings in the calibration window, the calibration state is shown graphically.

Some measurements have to be repeated over and over again ...

... therefore we added an Automation Interface to the Bode 100 right from the beginning. Today many customers are already using this Application Programming Interface (API) to build automated measurement setups involving the Bode 100.

Bode 100 can be controlled from COM compliant programming languages such as:

  • LabVIEW®
  • C#
  • VB.NET
  • Excel® with VBA
  • C++
  • TCL
  • Python®
  • Delphi®

Bode Analyzer Suite 3.0 features the latest Automation Interface version 3.0 that comes with several new features and advantages.

Find out more about the Bode Automation Interface by reading the Automation Interface Reference.

The Automation Interface is included in the Bode Analyzer Suite installer. Check out the Bode 100 download area.
