Usage:
Query only
Manual operation:
See
[:SOURce<hw>]:EBOX:CPRI:TX|RX:SIGNal<ch>:AXC:DRATe:ASSigned?
Queries the data rate assigned to the signal.
The assigned data rate depends on the signal group settings, i.e. on the repetition rate
and the number of active AxCs per group.
The assigned data rate is calculated with the formula:
Data Rate
assigned
[Mbit/s] = 3.84 [MHz] x 2 x I/Q Resolution (
∑
(AxC_on_count
grp
x Repe-
tition
grp
) /
∑
(Repetition
grp
))
Note:
In case of "Sync Pattern" signals, the assigned data rate depends on the pattern length
and the sample rate. It is calculated by the sample rate as shown:
Return values:
<Assigned>
float
Increment: 10000
*RST:
122880000
Example:
SOUR1:EBOX:CPRI:TX:SIGN:AXC:DRAT:ASS?
check the data rate of the first signal.
Response:
122.88
Mbit/s
this signal is transmitted with 122.88 Mbit/s data rate.
Usage:
Query only
[:SOURce<hw>]:EBOX:CPRI:TX|RX:SIGNal<ch>:AXC:DRATe:NEEDed?
Queries the data rate required from the signal.
This command applies to downlink.
Return values:
<Needed>
float
Increment: 10000
*RST:
122880000
Example:
SOUR1:EBOX:CPRI:TX:SIGN:AXC:DRAT:NEED?
check the data rate the first signal needs.
Response:
122.88
Mbit/s
this signal uses
122.88
Mbit/s data rate.
Usage:
Query only
[:SOURce<hw>]:EBOX:CPRI:TX|RX:SIGNal<ch>:AXC:DRATe:STATus?
Queries whether the assigned data rate fits to the required data rate.
