9412/9412A Communication Commands

 

Command Name

 

Parameters

 

Description

 

MODE 

0 = Continuous mode

 

1 = Burst mode 
2 = Duty Cycle mode 
3 = Single Shot mode 
4 = External Trigger mode 

Sets the pulse generator mode. 

GATE 

0 = off 
1 = active low 
2 = active high 

Enables the external trigger input to function as a gate 
controlling all outputs.  Cannot be used with external 
trigger mode. 

ToPer 

1000 - 99999999 

µ

s  

500 - 99999999 

µ

(400B)

 

Sets the To internal sync period, used only in Continu-
ous, Burst and Duty Cycle modes. 

DC:On 

1 - 10000 Sec 

Sets the on time, in seconds, for the Duty Cycle mode. 

DC:Off 

1 - 10000 Sec 

Sets the off time, in seconds, for the Duty Cycle mode. 

TRIG 

0 = falling edge 
1 = rising edge 

Sets the active edge of the Ext/Gate signal when used as 
an external trigger. 

CYCLES 

0 - 10000 cycles 

Sets the number of cycles for the Duty Cycle mode. 

#/BURST 

1 - 50000 pulses 

Sets the number pulses in the Burst mode. 

T1:Wid 

1 - 99999999 

µ

s  

Sets the pulse width, in microseconds, for Channel 1. 

T1:Dly 

0 - 99999999 

µ

Sets the delay, in microseconds, for Channel 1. 

T1:Pol 

0 = Negative  (active low) 
1 = Positive   (active high) 

Sets the polarity of the output for Channel 1. 

T2:Wid 

1 - 99999999 

µ

s  

Sets the pulse width, in microseconds, for Channel 2. 

T2:Dly 

0 - 99999999 

µ

Sets the delay, in microseconds, for Channel 2. Note: 
The delay is relative to Channel 1. 

T2:Pol 

0 = Negative  (active low) 
1 = Positive   (active high) 

Sets the polarity of the output for Channel 2. 

T2:Enable 

0 = Off 
1 = On 

Turns the output of Channel 2 on and off. 

T2:Gate 

0 = Off 
1 = Active low 
2 = Active high 

Enables the external input to act as a gate for Channel 2's 
output. 

T2:Wait 

0 - 10000 pulses 

Set the number of pulses to wait after starting T1  before 
enabling T2. Note: This is used to allow time for the la-
ser to stabilize when T1 is used as a flashlamp trigger 
and T2 is the Q-switch trigger. 

T2*n 

1 - 10000 

Sets the period of T2 relative to T1. The period of T2 is 
the period of T1 multiplied by n. 

BEEP 

1 - 1000 

Beeps the buzzer inside the 9412/9412A the specified 
number of times. 

RUN 

0 = Disable    
1 = Enable 

Enable / disables the pulse generator output.
