Connector diagrams
Standard oscilloscope connectors
The analog input channels have standard BNC connectors and standard input
impedances. They are therefore compatible with most oscilloscope probes including
x10 and switched x1/x10 variants. For optimum performance, always use the probes
supplied with your PicoScope.
Arbitrary waveform generator output
The built-in arbitrary waveform generator (AWG) can generate a waveform of almost
any shape. The generated waveform can be injected into the device you wish to test
and then analyzed as it progresses through the device to confirm correct operation, or
to highlight a fault.

If you are using the PicoScope 6 software, refer to the
PicoScope 6 User's Guide
for
information on how to configure the arbitrary waveform generator.

If you are writing your own software, refer to the

Digital inputs for mixed-signal oscilloscopes (D MSO models only)
Alongside the analog channels, the mixed-signal 3000D MSO Series oscilloscopes also
feature 16 digital inputs. The PicoScope software allows you to view both digital and
analog signals simultaneously. Your digital inputs are easily manageable, and can be
reordered, grouped, and renamed.
Features such as triggering and serial decoding can also be used on the digital
channels.
Digital inputs for PicoScope 3000D Series MSO models
External trigger (EXT) input (D models only)
The EXT
input can be used as a trigger source. Select it from the Trigger menu in the
PicoScope software, or by using a function call if you are writing your own software.
The EXT input uses dedicated circuitry, in combination with a software-configurable
threshold, to detect a trigger signal. This leaves the analog channels free for viewing
signals. The input characteristics of the EXT input are matched to a scope channel so
that the supplied, compensated probes can be used with the EXT input to give high
vertical accuracy.
Where trigger timing accuracy is critical, we recommend using one of the main input
channels as the trigger source. These channels use accurate digital triggering (to one
sample period) and have a vertical resolution of 1 LSB.
USB port
All models have a SuperSpeed USB 3.0 port for connection to a PC. See
for more information.
Earth terminal
External noise may sometimes interfere with your measurements if the PicoScope is
used with a computer which does not have a ground connection. If this is the case,
connect the earth terminal to an external ground point (for example, on the system
you are testing) to provide a ground reference for the oscilloscope.
