b. On the Main tab page, enter the exposure time, gain and switch to Gate
Mode. The number of spectra will be automatically set depending on the
number entered on the Sequential Gating Setup dialog box (Figure 49).

Note: In Gate Mode, the photocathode is biased on only for the time that each
gate pulse is applied. As a result, the tolerance to room light is higher in gated
operation than it is in Shutter Mode, but the risk of damaging overload from
intense light sources such as lasers remains.
12. After verifying all connections and equipment readiness, click on Acquire to
begin acquiring the spectra (or images).
13. Figure 52 displays the 3-D graph for a “Sequential-Repetitive" experiment with
Fixed Width and Variable Delay (as set in Figure 48 and Figure 49).
