The "channel spacing" determines the offset size of the adjacent and alternate

channels: 1st Alternate Channel = 2 x channel spacing, 3rd Alternate Channel =
4 x channel spacing.

The "channel spacing" determines the offset size of the adjacent and alternate

channels: 1st Alternate Channel = 2 x channel spacing, 2nd Alternate Channel =
3 x channel spacing.

(ACP)

(Low ACP Mode, dBc, typical)

[see table 8]

Supported Burst Types: Custom, Up Control 1 & 2, Up Normal,
Down Normal, Down Sync
Scramble Capabilities: Yes

14

Specifications apply for the frequency range, data rates and filter factors

(alpha) specified at power levels >=+4 dBm.

15

The "channel spacing" determines the offset size of the adjacent and alternate

channels: Adjacent Channel Offset = 1 x channel spacing, 1st Alternate Channel =
2 x channel spacing, 2nd Alternate Channel = 3 x channel spacing, 3rd Alternate
Channel = 4 x channel spacing.

16

ACP for TETRA is measured over a 25 kHz bandwidth, with an 18 kHz root-raised

cosine filter applied.
