This level of performance can be attained using the external I/Q inputs, provided the quality of the basebandsignal meets or exceeds that of the ESG baseband generator.2. Parentheses denote typical performance.3. Specifications apply at power levels ≤ +4 dBm [≤ +5 dBm for Option 506, and ≤ +8 dBm for Option UNB] withdefault scale factor of I/Q outputs.4. Valid after executing I/Q calibration and maintained within +/- 5 °C of the calibration temperature.5. ACP for TETRA is measured over a 25 kHz bandwidth, with an 18 kHz root raised cosine filter. Low ACP mode isvalid at power levels ≤ –1 dBm [≤ 1 dBm for Option 506 and ≤ +4 dBm for Option UNB].6. Specifications apply for the symbol rates, filter, filter factors [a or BbT] and default scaling factor specified foreach standard, and at power levels ≤ +7 dBm [≤ +10 dBm for Option UNB].7. The “channel spacing” determines the offset size of the adjacent and alternate channels: Adjacent channeloffset = 1 x channel spacing, 1st alternate channel = 2 x channel spacing, 2nd alternate channel = 3 xchannel spacing, etc.24
