7 Setting up Measurements
"Level (dBm)" setting to allow the E6610A to automatically adjust its input atten-
uation and gain to optimize Rx measurements. Range of allowed values is 0 to
80.00 dB.
— Level (dBm): Enter the power level at the Tx output of the RRH. This information
will be combined with the "Ext Attn" setting to allow the E6610A to auto-
matically adjust its input attenuation and gain to optimize Rx measurements.
After accounting for the "Ext Attn" setting, the allowed range of values is -80.00
to +5.00 dBm.
— Input check box: Enable or disable the RF Rx capture channel.
Configure RF TX Ports
Click on the "RF TX" tab to configure settings for the RF TX outputs, which are used to
test the receiver paths in the RRH.
— Freq (MHz): Enter the frequency for the RF Tx port, which is the RRH's Rx input
frequency. Note: Frequencies for RF TX 1 and RF TX 2 can be set inde-
pendently.
— Waveform: Select the uplink waveform file to be transmitted to the RRH's
receiver inputs. LTE test model FRC-A3 files are provided with the N5121A
LTE FDD and N5122A LTE TDD applications. This provides a QPSK signal
