12. PATTERN

This input can accept either a TTL/CMOS low to TTL/CMOS high or

TRIG IN

TTL/CMOS high to TTL/CMOS low edge trigger. With Option UN8

 

this input triggers the internal digital modulation pattern generator

 

to start a single pattern output or to stop and re-synchronize a

pattern that is being continuously output. With Option UND this input is the external trigger source for all ARB waveform generator triggers. With Option 201 this connector is used for system reset trigger input.

13.BURST GATE The BURST GATE IN connector accepts a TTL or CMOS signal for

IN

gating burst power in digital modulation applications. This female

 

BNC connector is present only on instruments with Options UND or

 

UN8. With Option 201 this connector is used for even second

 

synchronization input.

14.COHERENT This connector outputs RF that is not modulated with AM, pulse, or CARRIER OUT I/Q modulation, but that is modulated with FM or ΦM. This SMA

connector is present only on ESG-D and ESG-DP Series Signal Generators.

15.ALT PWR IN This BNC connector accepts a CMOS signal for synchronization of external data and alternate power signal timing. This connector is active only with Options UNA or 201. With Option 201 this connector is used for Long Code State Latch strobe input.

16.

EVENT 1

With Option UN8 turned on, this TTL/CMOS-compatible connector

 

 

outputs a pulse that can be used to trigger the start of a data

 

 

pattern, frame, or timeslot. With Option UN5 turned on, an even

 

 

second output is generated every two seconds indicating the

 

 

beginning of each short code sequence. With Option UND turned on,

 

 

a marker is output whenever a Marker 1 is turned on in the

 

 

waveform. With Option 201 you can select from several different

 

 

output signals for this connector.

17.

EVENT 2

This TTL/CMOS-compatible connector outputs a data enable signal

 

 

for gating external equipment. With Option UN5 turned on, a

 

 

marker is output every 26.67 ms, corresponding to the start of each

 

 

short code. With Option UND turned on, a marker is output

 

 

whenever a Marker 2 is turned on in the waveform. With

 

 

Option 201 this connector is used for system reset output.
