softkey to finish data entry if you are using the numeric keypad.
4. Set the burst period.
Press the Burst Period softkey and then set the period to 20 ms using the numeric keypad or the knob and cur-
sor keys. The burst period sets the time from the start of one burst to the start of the next burst. At this point, the
instrument outputs a continuous three-cycle burst at 20 ms intervals.
You can generate a single burst (with the specified count) by pressing the Trigger key. For more information, see
Trigger Sweep or Burst.
You can also use the external gate signal to create gated bursts, where a burst is produced while a gate signal is present
on the input.
Trigger Sweep or Burst
You can issue four different types of triggers from the front panel for sweeps and bursts:
Immediate or "automatic" (default): instrument outputs continuously when sweep or burst mode is selected.
l
External: triggering controlled by rear panel Trigger connector.
l
Manual: initiates one sweep or burst each time you press Trigger. Continue pressing Trigger to re-trigger instru-
l
ment.
Timer: issues one or more triggers a fixed time amount apart.
l
If sweep or burst is on, pressing Trigger displays the trigger menu. An illuminated Trigger key (solid or blinking) indi-
cates that one or both channels are in awaiting a manual trigger. Solid illumination occurs when trigger menu is
selected, and flashing illumination occurs when trigger menu is not selected. Trigger key is disabled when instrument
is in remote.
Pressing Trigger when it is solidly illuminated causes a manual trigger. Pressing Trigger when it is flashing selects the
trigger menu; a second press causes a manual trigger.
Store Instrument State
You can store instrument states in any number of state files, (extension .sta). You can do this for backup purposes, or
you can save your state to a USB drive and load it on another instrument to have instruments with matching con-
figurations. A stored state contains the selected function, frequency, amplitude, DC offset, duty cycle, symmetry, and
any modulation parameters in use. The instrument does not store volatile arbitrary waveforms.
