Uplink Channel (UARFCN)

Uplink Channel (UARFCN)

Last updated: October 19, 2012

Uplink Channel

The Uplink Channel setting specifies the uplink UTRA Absolute RF Channel Number (UARFCN). This automatically sets the test set's receivers to the expected UE transmit frequency.

The relationship between UARFCN and uplink frequency is described in 3GPP TS 25.101 section 5.

You can specify the uplink UARFCN in one of two ways:

To query the current uplink channel number via GPIB command, see CALL:STATus:UPLink:CHANnel? . Current Info, UL: Channel and Frequency is also displayed on the Channel (UARFCN) Information screen.

When in FDD Test operating mode, the expected uplink frequency can also be set by manually entering the Uplink Frequency (see Receiver Control ).
