RadioProcessor
Specifications
The RadioProcessor is currently available with a 75 MHz Analog-to-Digital (A/D) sampling clock frequency.
Specifications for this configuration are given in the table below. For information specific to a certain
RadioProcessor firmware revision, see Appendix VII or contact SpinCore Technologies, Inc.

Notes
(1): If the signal to be detected is very close to ¼ of the sampling rate, there will be problems with aliasing during the detection
process. To alleviate this problem, a slightly higher or lower clock speed can be used.
(2): Analog output voltage is factory adjustable up to 4V. See Transmitter Output Level section on the next page for more
information.
(3): Frequency resolution is 30 Hz when using an 80 MHz clock.
(4): Custom designs are available. Please contact SpinCore if you require more digital outputs (or DDS registers).
(5): This is the value seen without using termination. When the line is terminated with 50Ω, the output voltage will be slightly lower.
(6): This value is with the FIR filter Enabled. With FIR bypassed, min SW is 72 Hz. Some older designs have a min SW of 4.5 Hz
(1.2 kHz with FIR Enabled).
(7): This number is dependent on the A/D clock frequency (i.e., A/D clock frequency divided by 8). NOTE: when acquiring data
directly from A/D, the spectral width is ½ the A/D clock frequency.
(8): Fewer points may be observed, however, the number of points retrieved from board memory must be a multiple of 8k.
(9): 4096 maximum words for several firmware versions, including, 12-15. Please contact SpinCore for more information.
(10): Pulse resolution equals one clock period of the master clock oscillator.
(11): Minimum pulse width is five clock periods of the master clock oscillator. Maximum pulse width is 2^52 clock periods of the
master clock oscillator.
