Oscilloscope application notes / videos

Here you will find a collection of videos that will show you how to get the most out of PicoScope Oscilloscope Software.

Whether you’re a novice PicoScope user, someone who just wants to find out more about PicoScope, or one of the legion of long-term PicoScope users, these free-to-watch videos will help increase your knowledge and understanding.

Equivalent Time Sampling (ETS) for FPGA Phase Measurement (PicoScope 6000)

What's the use of ETS? If you're doing high-speed FPGA work, it can be helpful for measuring phase differences.

Using PicoScope AWG for Testing Serial Data Limits

Made easy! Import data from some channel, export it back out the AWG. You can vary the time & voltage mapping to see for example how your code deals with off-frequency IO timing, or different voltage levels. Part of my review of the PicoScope 6000.

Switching PSU Load Test - 8 vs 12 bit Resolution (PicoScope 5000)

The PicoScope 5000 Series allows you to dynamically change the ADC resolution. If you're trying to get a high dynamic range for example with a large spike in one part of the trace but you still want to see detail about the rest of the trace.

How to detect intermittent problems using Color Persistence mode

This video shows how to use Color Persistence mode with an oscilloscope to detect intermittent problems. In this example we use the PicoScope 4262. 

How to use an oscilloscope to measure the output level and gain of an audio amplifier

This video shows how to measure output level and gain of an audio amplifier using the PicoScope 4262. The oscilloscope's built-in signal generator is used as the test source. 

How to use an oscilloscope to measure the frequency response of an audio amplifier

Measuring the frequency response of an audio amplifier using the PicoScope 4262. Includes spot frequency tests and a frequency sweep test, both of which can be done using the instrument's built-in signal generator.

How to use an oscilloscope to measure distortion in a stereo amplifier

Measuring distortion in a stereo amplifier using the PicoScope 4262 USB Oscilloscope. Distortion harmonics can be detected even when the time-domain waveform looks clean.

How to measure the dynamic range of the PicoScope 4262 Oscilloscope

Measuring the dynamic range of the PicoScope 4262 using its built-in low-distortion signal generator. The PicoScope 4262 has more than enough dynamic range to capture these signals without adding significant noise or distortion of its own.

Frequency response measurement using the PicoScope 4262

A second example of frequency response measurement using the PicoScope 4262, this time showing the effect of an audio amplifier's HF cut-off filter.

PicoScope 6: Serial Decoding of CAN Bus Signals

Differential CAN bus signals are acquired and decoded using the serial decode feature in PicoScope 6.

PicoScope 6: Serial Decoding of SPI Bus Signals

In this video the three--wire SPI bus signal is displayed and decoded using the serial decode feature in PicoScope 6.

PicoScope 6: Serial Decoding of UART--RS232

This videos shows how to capture and display ASCII characters from an RS232 bus.

PicoScope Mixed Signal Oscilloscope -- Capturing multiple I2C Data events

This video shows how to use an oscilloscope to easily trigger and capture more than one packet of I2C for further investigation of multiple events. In this example we are using the PicoScope 2205 MSO.

PicoScope 6: Measuring the Total Power of an RF Pulse

This videos demonstrates how to use the total power measurement on an RF pulse in spectrum mode. 

PicoScope 6: Capturing High--Speed Serial Data

Capturing and analysing high--speed digital data requires careful considerations including choosing the correct termination, use of advanced triggers, and measuring jitter. 

Realtime NTSC decoding using Picoscope 2204

Realtime decoding of composite NTSC video signal from Raspberry Pi using the Picoscope 2204 USB oscilloscope and custom software I wrote. Screen recording causes some screen stutter Details coming up at http://codeandlife.com
