Oscilloscopes

Measurements and alarms in PicoScope 5

PicoScope has over thirty automated measurements. Oscilloscope measurements include frequency, rise time and pulse width. Spectrum measurements include THD, SFDR and SNR.

For each measurement, upper and lower alarm limits can be set. This makes it possible for example to set an alarm if a pulse width goes out of specification. To add an alarm, first add the Measurement you wish to use using

Settings | Measurements | Add

From the resulting dialog box enter minimum and maximum values to be used then click OK. From

Measurements | Options

you can select the action to occur on alarm, the choices are to either stop the scope (so capturing the error on the screen) or to sound an audible alarm.
