(SELECT SLOT...)
TCH
BURST TYPE
Selection of burst type used to configure the selected slot.
TCH Traffic channel burst
IEC/IEEE-bus
:SOUR:NADC:SLOT2:TYPE TCH
SLOT LEVEL
(UPLINK only)
Selection of level for selected slot.
OFF Maximum attenuation
IEC/IEEE
:SOUR:NADC:SLOT2:LEV OFF
FULL The level corresponds to the value indicated on
the SMIQ LEVEL display.
IEC/IEEE
:SOUR:NADC:SLOT2:LEV FULL
ATTEN The level is reduced by the value set under
SLOT ATTENUATION.
IEC/IEEE
:SOUR:NADC:SLOT2:LEV ATT
BURST STATE
(DOWNLINK only)
Substitute for parameter SLOT LEVEL for DOWNLINK.
ON The burst contents defined in the data fields are
sent in the selected slot.
IEC/IEEE-bus
:SOUR:NADC:SLOT2:LEV FULL
OFF Only 1s will be sent.
IEC/IEEE-bus
:SOUR:NADC:SLOT2:LEV OFF
Parameter SLOT LEVEL is omitted since the NADC base
station in downlink always sends with the same power in
each slot.
SET DEFAULT
Resets the subsequent parameters to the factory-set values.
IEC/IEEE-bus command
:SOUR:NADC:SLOT8:PRES
G
(UPLINK only)
Display of data contents in the 6 bit data field "Guard" in
hexadecimal form.
R
(UPLINK only)
Display of data contents in the 6 bit data field "Ramp".
DATA
Selection of data source for DATA fields. These fields are
regarded as a continuous field, ie a pseudo-random
sequence is fully continued from one DATA field to the next.
The following data sources are available:
PN.. PRBS data according to CCITT with periods
between 2
