Connecting to a W61PC Card

The W61PC card has four SMA signal inputs and a Mini-DIN connector:

Input / Output

Frequency Range Function

Input Voltage Range

AFIF#1- 3

50 Hz-25 MHz

AF or IF Input

2.0 mVrms – 0.5 Vrms

20 mVrms – 2.5 Vrms (with attenuator jumper)

Input impedance: 10 kOhm

IF70#4

52.5 MHz-87.5 MHz

IF input for SAT monitoring

50 mVrms - 5 Vrms

Input impedance: 50 Ohm

EXT-DEM

Max. 12 kbps

External Demodulator Input

[0 V, +5 V] to [-12 V, +12 V]

DIG

Max. 36 Mbps, Direct Input for DSP receivers (not yet supported)

-0.5 to +6.5 V

One or more of these inputs must be connected to the signal source(s) using a coaxial cable or a similar shielded cable. As an example a HF receiver may be connected to an AFIF connector and a satellite receiver to the IF70#4 connector.

To avoid distortion of the input signal the input voltage ranges listed above should be observed.

20 dB attenuation jumpers are located on the PCB close to the corresponding input connectors.

Below is an example configuration for a W61PC card setup:

The external FSK demodulator hardware is optional - it is only required if the customer wishes to use his own demodulator hardware.
