•
“Set CW” puts the RF chip to TX CW mode.
•
“Set Pattern” transmits
the specified 8-byte pattern forever. The byte
specified by the two leftmost digits is sent first. Each byte is sent LSB first
unless the “send MSB first” button in the framing panel is checked.
Manchester, scrambler, and differential encoder are bypassed (inversion
encoding applies if selected!).
•
“Set Random” transmits pseudo
-random data forever. (This is realized using
the scrambler.)
•
“RX 1010” performs measurement of bit error rate (BER).
Typically connect the RX to a signal generator sending an infinite 1010
stream, i.e. in FSK mode the generator should toggle between {+1, -1}*half
deviation.
In 4-FSK mode, the pattern {-3, -1, +1, +3}*half deviation should be applied.
The BER value can be measured with 3, 4 or 5 digit precision.
•
“TX 1010” transmits an
infinite 1010 stream suitable for “RX 1010” BER
measurement.
•
“RX PN9”, “TX PN9”, “RX PN15”, “TX PN15”, “RX PN17”, “TX PN17” are similar
to “RX 1010” and “TX 1010”, except that the BER measurement is performed
using a pseudo-random data stream. In PN9 mode, the data stream is
generated using the polynomial x

+x

+1, in PN15 mode, the polynomial
x

+x

+1 is used, and in PN17 mode, the polynomial x

+x
12
+1 is used.
