Extension Connector

A 9 pin female D-sub connector is available at the back of the Handyscope HS6
DIFF containing the following signals:
Pin Description
1 EXT 1 (LVTTL)
2 EXT 2 (LVTTL)
3 Probe Cal
Pins EXT 1 and EXT 2 are equipped with internal 1 kOhm pull-up resistors to 2.5 V.
These pins can simultaneously be used as inputs and outputs. Each pin can be
configured as external digital trigger input for the acquisition system of the Handy-
scope HS6 DIFF.
Pin 3, Probe Cal, has a 1 kHz, -1 V to 1 V square wave signal that can be used to
perform probe frequency compensations.
Pin 8, Power OUT, has the same potential as the Handyscope HS6 DIFF power
supply. When the Handyscope HS6 DIFF is USB powered, it is at USB power level.
When the Handyscope HS6 DIFF is externally powered, it is at the same level as
the external power input.
The External Clock In signal must be a 10 MHz ± 1% or a 16.369 MHz ± 1% 2.5 V
TTL signal.

CMI

The Handyscope HS6 DIFF has two Combine Multiple Instruments interface (CMI)
connectors at the rear of the instrument. These are used to combine multiple
instruments to a single combined instrument to perform fully synchronized mea-
surements. This requires one TP-C50H coupling cable per two instruments.
The CMI connectors use HDMI type C sockets, but are not HDMI compliant.
They can not be used to connect an HDMI device to the Handyscope HS6
DIFF.
