The firmware support of the R&S
ZVAX-TRM extension unit is based on the generic
devices functionality.
A generic device's control interface is declared in one or more device configuration
files, using the popular
*.json
file format). The following
top-level keys are supported:
●
"Header"
The
"Header"
object describes the content of the config file. Currently only its
"File Format"
key-value pair is evaluated and only the value
1.0
is accepted.
●
"Device Identification"
The
"Device Identification"
object describes the device properties the ana-
lyzer firmware has to consider when interacting with the device. Currently only its
"Settling Time"
key-value pair is evaluated. It describes the time (number of
seconds) the firmware must wait after sending a command sequence to the device.
●
"Commands"
The
"Commands"
array defines possible commands (or rather command sequen-
ces) the analyzer firmware can send to the device.
Each command (sequence) is specified by:
–
A
"Command Name"
(string value), identifying the command
–
A
Command List
array whose members (JSON objects {"Command":
"<Device command>"} represent the individual commands to be sent to the
device.
The
"Command Name"
value must be unique within a configuration file. It is used to
select the respective command sequence at the GUI or via remote control.
