3.1 CONTROLS 

AND CONNECTORS

The generator controls and connections are shown in
figure 3-1 and keyed to the following descriptions.

0

MODE Switch -

Selects one of the following eight

modes.

CONT - Continuous pulses at all output connectors.

TRIG  - DC level at all outputs until a suitable trig-
ger appears (see

 , 

 );

 then one or more

pulses occur,depending on mode and control settings.

GATE  -

DC level at all outputs until a suitable

trigger edge appears (see 

 , 

 );

 then pulses

occur until the trigger signal transverses the generator
trigger level again.

EXT WIDTH - DC level at all outputs until a

suitable trigger appears (see

 , 

 );

 then a

pulse occurs which has the duration of the trigger
signal.

TRIG BURST - DC level at all outputs until a
suitable trigger appears (see

 , 

 )

 to trigger a

gate time 

 ;

 then a fixed number of pulses occur

as determined by 

 and 

 .

CONT DBL -

 As for CONT except two pulses occur

for each pulse period. Time to second pulse is set by

0

5

TRIG DBL - As for TRIG except two pulses occur

in the one pulse period. Time to second pulse is set”

by
