3.2.1 System Status and Control
The
System Status and Control
section of the main form (refer to
on page
above) provides for control of the main functions of the system as well as status
information for the key operational settings of the link. This section is always visible when the
main form is displayed. The four subsections of the
System Status and Control
section are
Session Control
,
Link Status
, either
Base Unit Control
or
Remote Unit
Control
, and
System Messages
.
•
Session Control
: This subsection contains a control for status polling:
−
Status Polling
: This checkbox controls the status polling operation. When this
box is checked, status polling is enabled and the polling interval is based on the
setting on the ADK main form under
System Settings > Status Poll Rate (Hz)
(refer to
on page 9). This can be unchecked to reduce the
amount of digital disturbance when making sensitive measurements in a lab
environment (e.g., RX sensitivity tests).
•
Link Status
: This subsection displays the real-time setup and operational status of
the unit. All fields in this subsection are read-only.
−
Channel
: This field displays the frequency associated with the current channel.
−
A Divide Value
: This field is used in conjunction with the
M Divide Value
field to
set the synthesizer to the desired frequency. Refer to the
ZL70550 Programmer
User's Guide
for synthesizer frequency calculations.
−
M Divide Value

A Divide Value
field to
set the synthesizer to the desired frequency. Refer to the
ZL70550 Programmer
User's Guide
for synthesizer frequency calculations.
−
VCO Band
: Since the ZL70550 VCO can be used over a wide range of
frequencies, it is split into sixteen bands of operation. The
VCO Range
field
displays the VCO band.
•
Base Unit Control or Remote Unit Control
: This subsection
displays the real-time setup and operational status of the unit.
−
ZL70550 Registers

registers of the unit (refer to
on page 20).
−
Vsup 1
:
Config
: The
Vsup 1 Config
field allows the user to define the supply voltage for
the ZL70550 transceiver. The range is 1.45 V to 3.65 V.
•
System Messages
: The text box in the
System Messages
subsection at the bottom
of the form displays critical system messages. Typically, these are error messages
returning from an operation to help users understand operational problems. The
Clear
button clears any messages that are currently displayed in the text box.
