GROW/DAMP ENABLE
Enables coefficient set switching during data
acquisition.
REC. DOWNSAMPLE
Acquisition channel downsampling factor. This
downsampling process is completely decoupled form the processing
channel downsampling.
RECORD LENGTH
Number of samples to acquire during data acquisi-
tion. The value is limited to 131072 for blockRAM and 8388608 for
SRAM. Lengths up to 524288 will be read out every second. Longer
acquisition lengths will require multiple poll periods to read out.
GROW LENGTH
Number of samples to hold the coefficient set select
inverted during data acquisition.
HOLD-OFF
Number of groups of 4 samples to keep the coefficient set
select inverted before data acquisition. This can be used to delay data
acquisition and give slow oscillations time to grow.
TRIGGER SRC
Acquisition trigger source, internal or external. External
trigger is taken from TRIG2 input (NIM-level).
Acquire
Acquisition trigger pushbutton for internal trigger. This control is
no longer actively used - see the waveform panel (Fig. 11).
Arm
External trigger is only valid if the acquisition system is armed. Single-
event acquisitions on the external trigger can be performed by pushing
this button.
Auto re-arm
This option re-arms the acquisition system after each data
readout. This allows for continuous updates of beam data triggered by
external signal.
ACQ MEMORY
Selects which memory, FPGA blockRAM or SRAM is
used for acquisition.
MEMORY read
Reads out the results of the last acquisition and places
them in a file on the IOC.
Coefficients
Opens FIR coefficients control panel.
Timing
Opens timing control panel.
