Controls Description
AUX OUT REF OUT EXT REF IN
For MSO/DPO70000C and MSO/DPO70000DX instruments:
Use the AUX OUT connector to obtain a TTL-compatible,
negative polarity pulse when the instrument triggers or when
certain other events occur, such as a mask test failure or
completion.
Use the REF OUT connector to obtain a copy of the internal
reference.
Use the EXT REF IN connector to synchronize the instrument
time base to an external 9.8 – 10.2 MHz reference frequency
source. When not using the external reference, disconnect
signals from the EXT REF IN BNC connector.
Aux Out Ext Ref In Ref Clock Out
For DPO70000SX instruments:
Use the Aux Out connector to obtain a TTL-compatible,
negative polarity pulse when the instrument triggers or when
certain other events occur, such as a mask test failure or
completion.
Use the Ref Clock Out connector to obtain a copy of the
internal reference.
Use the Ext Ref In connector to synchronize the instrument
time base to an external 9.8 – 10.2 MHz reference frequency
source. When not using the external reference, disconnect
signals from the Ext Ref In BNC connector.
For MSO/DPO5000B instruments:
Use the Probe Power to input the probe power.
Use the REF IN to input the external reference. When not using
the external reference, disconnect signals from the REF IN
BNC connector.
Use the AUX OUT connector to obtain a TTL-compatible,
negative polarity pulse when the instrument triggers or when
certain other events occur, such as a mask test failure or
completion. You may also set the AUX OUT connector to
obtain a copy of the internal reference.
Use the GPIB connector to connect the instrument to a GPIB
controller for GPIB operation.
NOTE. The GPIB connector is available on all instruments
except MSO/DPO5000B and DPO70000SX Series instruments.
This connector is not used.
Use the DVI-I Video port (some instruments have a DVI-D
Video port) to send the instrument display to a projector or to a
flat-panel LCD monitor.
