Input

mode ..................................A four position rotary switch selects the source of the 

operation control signal.

continuous on ............provides a continuously running internal time base 

established by the setting of the eVent interVAl controls.

eXt sYnc ...........................replaces the eVent interVAl time base by an external, 

user-provided signal.         

sinGle eVent ..................replaces the eVent interVAl time base by a one-time 

signal provided by the user pressing the push button.

eXt GAtes .........................is the same as the continuous on mode, except that the 

internal time base is only on when the appropriate signal is 
applied to either of the two eXt GAtes connectors.  

eXt sYnc ...........................Bnc connector input for an external signal to replace the 

internal eVent interVAl time base. connector is only 
active when selected by the mode switch. the signal should 
be positive on the center pin, referenced to the shell. 

sinGle eVent ..................A momentary push-button switch provides a single pulse 

or sequence of pulses each time the switch is pressed. the 
switch is only active when selected by the mode switch. 

eXt GAtes .........................two Bnc connectors provide external signal input, which 

switches the internal eVent interVAl time base on and off. 
the connectors are only active when selected by the mode 
switch. the VoltAGe signal should be positive on the center 
pin, referenced to the shell. the sWitcH signal is a short-
circuit between the center pin and the shell.
