Model 6220/6221 Reference Manual
1. INIT
This command is used to initiate one trigger cycle and take the unit out of the
idle state.
2. ABOR
This command resets the trigger system. If a sweep is in progress, it will be
halted and the source value set to zero. The operate state, however, will be
left on. The sweep is still armed, and can be started again with another INIT
command (i.e., - no re-arming is needed).
3. ARM:SOUR <name>
This command selects the ARM layer event detector control source:
IMMediate, TIMer, BUS, TLINk, NSTest, PSTest, BSTest, or MANual.
4. ARM:SIGN
This command is used to bypass the ARM layer control source and move on
to the next layer in the trigger model (the TRIGger layer event detection in this
case).
5. ARM:TIM <n>
This command selects the ARM layer timer interval in the range of 0 to
99999.99 sec. with 1 msec resolution.
6. ARM:DIR <name>
This command enables (SOURce) or disables (ACCeptor) the ARM source
bypass.
7. ARM:ILIN <NRf>
This command selects the ARM layer input signal line: 1, 2, 3, 4, 5, or 6.
8. ARM:OLIN <NRf>
This command selects the ARM layer input signal line: 1, 2, 3, 4, 5, or 6. Note
that for the Model 6221 only, the trigger output line and phase marker
(SOUR:WAVE:PMAR:OLIN) lines cannot be the same, or a -221 Settings
Conflict error will occur. (See
9. ARM:OUTP <name>
This command selects when to output the ARM layer trigger. Available selec-
tions include TEXit (output when exiting trigger layer), TENTer (output when
entering trigger layer), or NONE (disabled).
10. TRIG:SOUR <name>
This command selects the TRIG layer event detector control source:
IMMediate and TLINk.
11. TRIG:SIGN
This command is used to bypass the TRIGger layer control source and move
on to the next layer in the trigger model (the device action block in this case).
