Data Type
This field selects the data type. This field appears only when Traffic Data
Mode
is set to Svc Opt 1, Svc Opt 3, or 32768.
• PRBS - a pseudorandom bit sequence.
• Echo - a reformatted and returned traffic packet (originated by the MSUT, received
and reformatted by the Test Set, then returned to the MSUT).
• 1 kHz Tone - a mathematically generated 1 kHz sine wave fed through a voice coder
by simulation software.
• 400Hz - a vocoded 400 Hz tone sent as the forward traffic data.
• Chirp - a vocoded chirp, with a duration of approximately 3 seconds, sent on the
forward traffic channel. The Chirp repeats after about 0.5 seconds delay.
GPIB Example
“CDMA:CALL:TRAFfic:DATA:TYPE ‘PRBS’“
selects PRBS.
Operating Considerations
The 1 kHz Tone, 400 Hz, and audio Chirp require the mobile station to have an IS-
96-A vocoder. Some mobile stations will distort the 1 kHz tone after a few
seconds.
