High Deviation – An unframed maximum frequency deviation test pattern of a continuously repeating
stream of high deviation symbols (+3, +3, -3, -3, …).
Low Deviation – An unframed test pattern of a continuously repeating stream of low deviation symbols
(+1, +1, -1, -1, …) for a 1/3 maximum frequency deviation.
Interference – The unframed standard interference test pattern as defined by the phase 2 standard and
described by the phase 1 (C4FM) standard as yielding a silence output at the receiver vocoder and balanced
to have approximately equal positive and negative signal deviations.
Modulation Type (P25 II submenu)
Select the desired type of modulation for the generated signal required by the receiver: HCPM or
HDQPSK.
Modulation Mode (P25 II submenu)
A horizontal submenu provides choice of Off, Continuous, or Burst mode for the selected Test Pattern
modulation.
Logical Channel (P25 II submenu)
Selects which logical channel for the transmitter to use (HCPM only), with ramp down to no power
(unused null slot) and ramp up to the next used slot. The logical channel uses either time slot according to
the asymmetrical superframe format; see Table 2.2.7.8.1.4-1. P25 Phase 2 Logical Channels (Inbound).
