PCI-CTR05

-1
If two or more boards of this type are physically present in the target PC, enter
the PCI slot number of the board associated with this driver block.
PCI-CTR05 FM Capture
This block programs the AMD9513A for capturing FM signals.
There is one output for relative frequency compared to the base frequency. To
get the actual frequency, multiply the base frequency by the relative frequency.

Driver Block Parameters
Counter - From the list, choose 1, 2, 3, 4 or 5. This selects which counter the
driver block uses to determine the FM. In each case, one block is needed for
each counter.
Frequency Base - From the list, choose F1=1MHz, F2=100kHz, F3=10kHz,
F4=1kHz, or F5=100Hz to set the base frequency. The XTAL frequency is
assumed to be 1MHz, therefore the jumper on the PCI-CTR05 has to be in
position 1MHz not 5MHz.
Sample Time - Enter the base sample time or a multiple of the base sample
time. The sample time indicates the update rate of registration on the input
(Duty Cycle)
PCI Slot (-1:autosearch) - Enter a number between -1 and n.
If only one board of this type is physically present in the target PC, enter
-1
If two or more boards of this type are physically present in the target PC, enter
the PCI slot number of the board associated with this driver block.
