3.10 Power-On Settings
At power-on, the pulse generator performs a diagnostic self-test procedure to check itself for errors. When the pulse
generator finishes the diagnostic self-test routine, it enters the local state (LOGS) and assumes power-on default
settings if the POWER-ON setting is at 0. You can program the pulse generator for any settings you want at power
on, as described earlier in this section.
The factory default settings are:
Power-on Default Settings

FALL 5 ns Pulse fall time
Table 3-2
NOTE: Power-on settings cannot restore the status of output at power-on, meaning if the output is ON, power-on settings
cannot recall it to be ON at start up. This setting will always remain OFF and power on, which is same as the default setup
indicated above in Table 3-2. Although the output status can be stored into memory for recall using the store/recall
functions, it cannot be recalled for a power-on setting start up. This is due to safety concerns as sensitive devices that are
connected to the outputs of the generator may accidentally be damaged at power-on if the power-on configurations are not
set properly (i.e. Amplitude level set too high for power-on may easily damage a sensitive device by accident).
3.11 Memory
The pulse generator uses a non-volatile FLASH memory for storing front panel settings. Up to 100 front panel
settings can be stored.
3.12 Displaying Errors
At power-on, the waveform generator performs a diagnostic routine to check itself for problems. If the diagnostic
