Key Sequence: Amplitude
PTC-ACSES Analyzer Amplitude Menu
Ref Level: Sets the reference power level at the top of the display when Auto Range is Off.
Scale: Scale sets the number of dB per division in the y‑axis of the graticule. Enter a value from 1 dB per division to 15 dB per division using the keypad, the arrow keys, or the rotary knob. The y‑axis power scale is shown on the left side of the display when viewing the Spectrum Graph.
Note: The Scale Menu is displayed when PTC-ACSES Coverage (Measurement > PTC-ACSES Coverage) is selected.
Rx Power Offset: Sets the receiver (RF IN connection) external attenuation or gain. Press the Rx Power Offset submenu key and select
a value from 0 dB to 100 dB then select either dB External Loss or
dB External Gain.
Auto Rx Range: Pressing this submenu key toggles between On and Off. When On, this function automatically adjusts the pre-amplifier based on the input signal. This only has 3 unique settings:
Ref level -4 with Preamp Off
Ref level -41 with Preamp Off
Ref level -41 with Preamp ON
Adjust Rx Range: When Auto Rx Range is Off, pressing Adjust Rx Range sets the Reference Level automatically for the current measurement.
Tx Output Lvl: Sets the output power of the Signal Generator
(0 dBm or 1 mW or 223 mV max).
Tx Power Offset: Sets the transmitter (Signal Generator Out connection) external attenuation or gain. Press the Tx Power Offset submenu key and select a value from 0 dB to 100 dB then select either dB External Loss or dB External Gain.
Units: Opens to Units Submenu.
Rx Units: Sets the unit of measure (dBm, watts, or volts) for Received Power in the Summary Graph and the Squelch Level.
Tx Units: Sets the unit of measure (dBm, watts, or volts) for the Signal Generator (Tx Output Lvl submenu).

Note: This menu displayed when PTC-ACSES Coverage (Measurement > PTC-ACSES Coverage) is selected.
RSSI Scale: Sets the number of dB per division in the y-axis power scale of the RSSI vs. Time graph in Coverage measurement. Enter a value from 1 dB per division to 15 dB per division using the keypad, the arrow keys, or the rotary knob.
BER Ref: Sets the BER reference percentage value at the top of the y-axis in the BER vs. Time graph in Coverage measurement. Enter a value from 1.00 % to 100.00 % using the keypad, the arrow keys, or the rotary knob.
EVM Ref: Sets the EVM reference percentage value. Enter a value from 1.00 % to 100.00 % using the keypad, the arrow keys, or the rotary knob.
