Return values:
<Assign>
integer
Range:
1 to 24
Increment: 1
*RST:
1
Example:
SOUR1:EBOX:CPRI:TX:SIGN2:AXC:COUN:ASS?
check the data rate and the AxCs assigned to the second signal.
Response:
3 / 368.40
Mbit/s
this signal requires 3 AxCs and a data rate of 368.4 Mbit/s.
To checkup, ask whether the allocated values fit to the required
values:
SOUR1:EBOX:CPRI:TX:SIGN2:AXC:DRAT:STAT?
Response:
0
if OK,
1
if not OK
Usage:
Query only
Manual operation:
See
[:SOURce<hw>]:EBOX:CPRI:TX|RX:SIGNal<ch>:AXC:COUNt:NEEDed?
Queries the needed number of AxCs and the required data rate.
Depending on the sample rate, a signal needs one or more AxCs to carry its I/Q data. If
possible, R&S
DigIConf automatically assigns the number of needed AxCs to the signal.
Note:
The maximum number of AxCs for all signals is 24.
The needed number of AxCs is calculated with the formula:
AxCs
needed
= ceil (Sample Rate x Oversampling / 3.84 [MHz])
The data rate is calculated with the formula:
Data Rate
needed
[Mbit/s] = Sample Rate x Oversampling x 2 x I/Q Resolution
Note:
For signal source "Pattern" the needed number of AxCs is 1.
Return values:
<Needed>
integer
Range:
1 to 24
Increment: 1
*RST:
1
Example:
SOUR1:EBOX:CPRI:TX:SIGN2:AXC:COUN:NEED?
check the data rate and the AxCs needed from the second signal.
Response:
3 / 358.40
Mbit/s
this signal requires '3' AxCs and a data rate of '358.4' Mbit/s'.
To checkup, ask whether the needed values fit to the assigned
values:
SOUR1:EBOX:CPRI:TX:SIGN2:AXC:DRAT:STAT?
Response:
0
if OK,
1
if not OK
