If ADD OCNS is set to ON,
•
channels 15 to 30 of base station 1 are automatically set as shown in the table above
and
•
the power of the OCNS component is adjusted automatically so that the powers of the OCNS
channels and the powers of the non-OCNS channels of base station 1 add up to yield a sum power
of linear 1.
The settings for the 16 OCNS channels are READ ONLY settings, i.e. they cannot be modified. In the
channel table, the OCNS channels are marked by an "O" after the channel number.
If the setting of a non-OCNS channel is modified, the power of the OCNS channels is adjusted
immediately. If adjustment is not possible because the powers of the non-OCNS channels already add
up to 0 dB or higher, the OCNS channels are set to -60 dB. In this case an error message is output
when WCDMA/3GPP is switched on.

SEQUENCE LENGTH
The maximum sequence length not only depends on free DGEN list memory
space but also decisively on the ENHANCED P-CCPCH/BCH status and,
where applicable, on the number of DPCHs:
ENHANCED P-CCPCH/BCH STATE = OFF
1 DPCH:
1022 frames
2 DPCHs:
511 frames
3 DPCHs:
341 frames
4 DPCHs:
255 frames
ENHANCED P-CCPCH/BCH STATE = ON
SYMBOL RATE DPCH
≤
30 ksps:
2044 frames
SYMBOL RATE DPCH > 30 ksps:
500 frames
New IEC/IEEE-Bus Commands
[:SOURce]:DM:IQ:FILTer:FREQuency 850 kHz, 2.5 MHz, 5 MHz, 7.5 MHz, 10 MHz
With this command, an IQ filter with the required cutoff frequency is selected. The command is
available, with option SMIQB47 (LOW ACP for IS-95 CDMA and W-CDMA) installed, for cutoff
frequencies 850 kHz, 2.5 MHz and 5 MHz. With model SMIQ03HD, cutoff frequencies 2.5 MHz,
5 MHz, 7.5 MHz and 10 MHz are available.
Example:
:SOUR:DM:IQ:FILT:FREQ 2.5MHZ
*RST value is 2.5 MHz
[:SOURce]:DM:IQ:HACLr:STATe ON | OFF
This command switches the option SMIQB57 on or off.
Example:
:SOUR:DM:IQ:HACL:STAT ON
*RST value is OFF
