TFCI Pattern

[:SOURce]:RADio:WCDMa:TGPP[:BBG]:DLINk:DPCH[1]|2|3|4:TFCI:PATTern <0 to

0x3FF>

[:SOURce]:RADio:WCDMa:TGPP[:BBG]:DLINk:DPCH[1]|2|3|4:TFCI:PATTern?

This command sets a 10-bit pattern for the transport format combination indicator (TFCI).

The TFCI is optional and describes the services in use (for example, voice and data).

Range: 0 to 0x3FF

*RST: 0

Timing Offset

[:SOURce]:RADio:WCDMa:TGPP[:BBG]:DLINk:DPCH[1]|2|3|4:TOFFset <0 to 149>

[:SOURce]:RADio:WCDMa:TGPP[:BBG]:DLINk:DPCH[1]|2|3|4:TOFFset?

This command adjusts the timing offset for the DPCH physical channel. The offset is in

chips.

Range: 0 to 149

*RST: 0

TPC Pattern

[:SOURce]:RADio:WCDMa:TGPP[:BBG]:DLINk:DPCH[1]|2|3|4:TPC:

PATTern UDOWn|DUP|UALL|DALL

[:SOURce]:RADio:WCDMa:TGPP[:BBG]:DLINk:DPCH[1]|2|3|4:TPC:PATTern?

This command controls the power of the users equipment (UE). The increase/decrease

direction for UE power level changes is determined by the TPC Pattern. The power can be

stepped all up, stepped all down, alternately step up then down, or step down then up.

*RST: Up/Down

TPC Pattern Steps

[:SOURce]:RADio:WCDMa:TGPP[:BBG]:DLINk:DPCH[1]|2|3|4:TPC:NUMSteps <1 - 80>

[:SOURce]:RADio:WCDMa:TGPP[:BBG]:DLINk:DPCH[1]|2|3|4:TPC:NUMSteps?

This command sets the number of 1 dB steps for increasing/decreasing the UE power. The

command is used with the TPC Patterns Up/Down (UDOWn) or Down/Up (DUP) and is the

number of 1 db steps taken before the increasing/decreasing power direction changes. The

command causes the UE power level to continually increase and decrease by the number of

1 dB steps assigned.

Range: 1 to 80

*RST: 1
