Retrieving results for disabled views
In some measurements it is possible to disable individual views and results in order to
gain measurement speed. The
READ...?
and
FETCh...?
queries act differently on
disabled views:
●
A
FETCh...?
command leaves the view in the unchanged (disabled) state and
returns NCAP (not captured) results. The view must be enabled explicitly to obtain
valid results.
●
A
READ...?
command enables the view implicitly and returns valid results. After
program execution, the view returns to the disabled state.
6.4.3 Signaling Generator Control
The commands used to control the RF generators of the different signaling applications
are analogous to the generator control commands explained in section
chapter 6.4.1,
"Generator Control" , on page 137. A signaling generator is in one of the following cell
states:
●
OFF : Signaling generator turned off, resources either released or (partially) reserved
from the last time the generator was turned on.
●
PENDing : Signaling generator turned on, but still waiting for resource allocation,
adjustment, hardware switching. No cell signal is available at the selected output
connector.
●
ON : Signaling generator turned on, with all necessary adjustments finished. A cell
signal to which a mobile station can synchronize is available at the selected output
connector.
The OFF and PENDing/ON states correspond to the status indication "Off" and "On" in
the generator softkeys. The relationship between generator commands and generator
states is shown in the following diagram:
