Data Outputs
The M8195A is always delivered with four physically available differential Data
Outputs of the Digital to Analog Converter (DAC). The analog DAC outputs are
labelled with DATA OUT CHANNEL 1, DATA OUT CHANNEL 2; DATA OUT CHANNEL
3, DATA OUT CHANNEL 4. Depending on the channel option (-001 or -002 or -004)
that has been installed, the M8195A one, two, or four differential analog outputs of
the Digital to Analog Converters (DAC) are enabled for data generation.
Option -001: The differential output DATA OUT CHANNEL 1 is enabled for analog
data generation. Also, one or two digital markers can be generated at DATA OUT
CHANNEL 3 and DATA OUT CHANNEL 4.
Option -002: The selected Instrument Mode (see section Instrument Modes)
determines, which channels are enabled for analog data and marker generation.
 In ‘Dual Channel’ mode the differential outputs DATA OUT CHANNEL 1 and
DATA CHANNEL 4 are enabled for analog data generation. DATA OUT
CHANNEL 2 and DATA OUT CHANNEL 3 are disabled.
 In ‘Dual Channel with Marker’ mode the differential outputs DATA OUT
CHANNEL 1 and DATA OUT CHANNEL 2 are enabled for analog data
generation. One or two digital markers can be generated at DATA OUT
CHANNEL 3 and DATA OUT CHANNEL 4.
 In ‘Dual Channel Duplicate’ mode the differential outputs DATA OUT
CHANNEL 1, DATA OUT CHANNEL 2, DATA OUT CHANNEL 3 and DATA
OUT CHANNEL 4 are enabled for analog data generation.
Option -004: The differential outputs DATA OUT CHANNEL 1, DATA OUT CHANNEL
2, DATA OUT CHANNEL 3 and DATA OUT CHANNEL 4 are enabled for analog data
generation.
Note: The Data Outputs can be used differentially or single-ended. In case the output
is used single-ended, the unused output must be terminated with 50 Ohm to GND to
achieve optimum signal quality.
TRIG IN
The Trigger Input has a combined functionality as Trigger or Gate and is used to start
the M8195A by an external signal. This input is defined in detail in the chapter
Sequencing
EVENT IN
The Event Input (EVENT IN) is used to e.g. step through segments or scenarios by an
external signal. This input is defined in detail in the chapter Sequencing.
REF CLK IN
The Reference Clock Input can be used to synchronize to an external clock. The input
frequency can vary between 10MHz and 17 GHz.
REF CLK OUT
The Reference Clock Output can be used to synchronize a DUT to the M8195A. The
adjustable output frequency covers a large frequency range.
