Field Strength This measurement allows the use of an antenna with known gain characteristics and measures the field strength over the frequency range of the antenna in units of dBm/m2, dBV/m, dBmV/m, dBµV/m, Volt/m or watts/m2. Opens the “Field Strength Menu” on page 3‑36. OCC BW Opens the “OCC BW Menu” on page 3‑36. Select either % or dBc method of occupied bandwidth measurement. Channel Power Activates the Channel Power measurement function. Opens the “Channel Power Menu” on page 3‑37. ACPR Accesses a menu of Adjacent Channel Power Ratio measurement options. See the “ACPR Menu” on page 3‑38. AM/FM Demod The user can select AM, Narrow Band FM (300 µs de-emphasis), Wide Band FM (50 µs de-emphasis), Upper Sideband or Lower Sideband. See the “AM/FM Demod Menu” on page 3‑39. C/I The Carrier to Interference ratio is a two-step measurement sequence that first measures the amplitude of a carrier, then, with the carrier turned off, measures the amplitude of all other interfering signals within the channel bandwidth. See the “C/I Menu” on page 3‑40. Measurement Off Turns the measurement off. More: Opens the “Measure 2/2 Menu” on page 3‑41.
