Figure 2: Front panel features
1) Power switch
This momentary-on lighted switch turns iGp-5120F on
and off. From the off condition, the unit will take 25–30 seconds to fully
boot. Shutdown time after power switch actuation is 5–10 seconds.
2) Low-speed DAC
This 16-pin connector provides 7 general-purpose ana-
log outputs. DAC settings are adjustable via experimental physics and
industrial control system (EPICS).
3) Low-speed ADC
This 16-pin input connector is provided for measuring
up to 8 external analog channels with 12-bit resolution.
4) Fast ADC
Two SMA connectors accept the differential inputs for the
high-speed ADC. When a single input is used the full-scale (FS) swing
is 195 mV peak-to-peak. Differential mode swing is 97.5 mV peak-to-
peak.
5) RF Clock
This input accepts the high stability bunch crossing clock sig-
nal (RF clock). Nominal input level is -3 dBm. The signal is internally
AC coupled.
6) Fiducial
This input receives the revolution fiducial. Input is expected
to be NIM-level. Active edge is the 0 to
−
0
.
8 V transition. The signal
must be stable within one RF period for reliable operation.
7) Trigger 1
This input is currently unused.
8) Trigger 2
This NIM-level input is used as an external trigger for data
acquisition.
9) LEDs
Eight front-panel LEDs provide indications of system activity and
operating status.
