Use the Cleverscope Frequency Response Analyser to measure and then save FRA data points to a text file for analysis with an external program such as Excel or Matlab. We also show how you can use the AddRef to see a family of captured curves.

Use the Cleverscope Frequency Response Analyser to measure the Gain/Phase response of a Minicircuits BBP-30+ bandpass filter. This video shows you how to connect up a CS328A-FRA to measure the Gain/Phase of the Minircircuits filter over the frequency range 1 MHz - 65 MHz.

Use the Cleverscope Frequency Response Analyser to measure the Gain/Phase of a power supply. This video shows you how to connect up a CS328A-FRA to measure the Gain/Phase of an LTC3589 over the frequency range 20 Hz - 1 MHz.

Use the Cleverscope Frequency Response Analyser to measure the Power Supply Rejection Ratio (PSRR) of a power supply with the CS1070 Power Amplifier. It can manage up to 1A output current over a voltage range of -18V to +30V over a frequency range of DC - 52 MHz. This is sufficient to directly measure many power supplies. If this is not enough, you can inject across a low value series resistor (eg 0.1 ohm). This video shows you how to connect up a CS328A-FRA and CS1070 to measure the PSRR of an LTC3589 over the frequency range 200 Hz - 10 MHz.

Use the Cleverscope Frequency Response Analyser to measure the input impedance of a power supply with the CS1070 Power Amplifier. It can manage up to 1A output current over a voltage range of -18V to +30V over a frequency range of DC - 52 MHz. This is sufficient to directly measure many power supplies. If this is not enough, you can inject across a low value series resistor (eg 0.1 ohm). This video shows you how to connect up a CS328A-FRA and CS1070 to measure the Input impedance of an LTC3589 over the frequency range 200 Hz - 10 MHz.

This short video shows you how to connect up a 4 channel Cleverscope, and use Ethernet connections.

Use Cleverscope to measure the Gain Phase response of a network. Results are displayed in linear or log form, with linear or log frequency axis. Phase can be displayed in radians or degrees, and unwrapped to achieve a continuous plot. The internal 0-10 MHz sig gen, or an external sig gen can be used.

Copy and paste with Cleverscope is fast and powerful. You realize how useful it is after going back to find crucial information in the pasted graph. The same goes for File Save. Not much more effort than that, but could save you heaps of time and effort later in reproducing what you've already done.

Cleverscope Tour takes you through some of the capabilities of the Cleverscope application such as Charting, Protocol Decode, Spectrum Analysis, Matlab and Excel live link and copy and paste.

Evaluating the Gain/Phase response of a switch mode power supply can be difficult because of the large amounts of switching noise. The Cleverscope application provides a synchronous Gain/Phase facility using the built in Signal Generator, and advanced DSP to automatically plot the Gain/Phase response. The adaptive signal generator output level mode uses the coherence between the stimulus and response values to achieve a good response plot. This tour is a step by step guide on measuring a switch mode power supply gain/phase response.

Use the Cleverscope Frequency Response Analyser to measure low impedances (1mOhm - 20 Ohm) including on live Power Supplies. This video shows you how to connect up a CS328A-FRA and measure the Output impedance of an LTC3589 over the frequency range 20 Hz - 1 MHz.

You can use Charting to stream captured samples to disk continuously at up to 1.5 Msps. The maximum capture size is around 200 G samples. After having captured you can zoom and pan very quickly to find the features important to you. This video shows you how. You can capture mixed signal analog and digital at the same time.

With display docking you can move all the Cleverscope windows in one group by moving the Cleverscope Control Panel. You can also minimize and restore as a group by minimizing just the Control Panel. This video shows you how.

This streaming tour shows Cleverscope streaming more than 38 G Samples to disk at 1 MSPS with 14 bits resolution and ENOB, all the while looking at the signal using Spectrum Analysis, the Tracking Display, Protocol Analysis and Signal Information. We quickly pan and zoom through the more than 10 hours of recorded signal and show save and load from disk for later review. We know of no other oscilloscope that can do this.

Cleverscope has made a new FRA control panel to make it easy to use Frequency Response Analysis (FRA) on a Cleverscope. Using the new CS701 isolated signal generator you can measure the power supply system stability, do gain phase plots of feedback loops, amplifiers and filters, and measure the impedance of components. You can also measure mechanical system stability. The CS701 and FRA control work over 0.1 Hz to 65 MHz. This video is a simple tutorial on FRA and how to use a Cleverscope to do it.

A first look at using the Cleverscope CS701 isolated Signal Generator operating with a very low 200uV rms level. We see 25 dB dynamic range, and flat response. This shows that the CS701 can be used to excite the feedback path in power supplies with a very wide dynamic range - from 200uV to 2V rms, with full 300 V RMS isolation. No need for an isolating transformer, and the current drive need to magnetize it. Simple connect to a small value resistor in the feedback path - anywhere on the power supply to verify gain and phase over a frequency range of 0Hz to 65 Mhz.

The Cleverscope Scope Display sets the amplitude range presented to the Analog to Digital Converter (ADC). You can type values directly onto the axis, use the expand/contract buttons, keyboard shortcuts, or the zoom tools. This video shows you how.

We use the FRA panel to measure the Impedance and Capacitance/Inductance of components such as capacitors, inductors, transformers and PCB's.

This video shows how you set up a filter, and use Cleverscope to export filtered results to Matlab to display a live spectrogram.

We have finally added Reference Plots and Persistence to the Spectrum Display. Watch this video to see it in action. Very useful when comparing FRA plots, or checking on stability or occupied bandwidth.

The FRA probe calibration procedure corrects for amplitude, gain and phase of the probes used to measure system frequency response, impedance or capacitance and inductance. After doing a Probe calibration you will achieve a flat gain/phase response with directly connected probes, ensuring that the responses you measure are those of your system, and not the probes.

The FRA BNC cable calibration procedure corrects for amplitude, gain and phase of the BNC cables and terminations used to measure system frequency response, impedance or capacitance and inductance. After doing a BNC cable calibration you will achieve a flat gain/phase response with directly connected BNC cables, ensuring that the responses you measure are those of your system, and not the cables and terminations.

The FRA BNC Fixture calibration procedure corrects for amplitude, gain and phase errors introduced by a test fixture. In addition we can compensate for the open circuit capacitance of the fixture. This video shows you how to simply calibrate a fixture, and then shows you the results with three 0603 SMT capacitors. You can use the fixture to reliably measure component values up to 65 MHz.

You can use the 'AddRef' persistence command to make a family of curves, and then step around them, and make further measurements as needed. This video shows you how to collect a family of Gain/Phase plots for a TI 5V 2.5A power supply, as the load current is varied from 2.5A to 1A and then 0.5A.
