SWR and return loss
Reflection coefficient magnitude and angle
For fastest throughput, set the unit into R-X mode (D101) and perform
calculations to other formats in the Terminal software.
The contents of save memory locations can be loaded into the terminal.
All save memory locations contain the instrument settings of the VIA Bravo
MRI unit, while only some of the locations contain saved data.
Also the entire unit setup data can be extracted in a fixed format block.
9.3.1.1 Data Request Commands
9.3.1.1.1 R
Send a block of measured data (data dump). The response is dependent
upon the type of data being sent out of the unit. The type of data may be set
by one of the setup commands (S100) or is determined by the left plot on the
unit. This command requires no EOS marker, but one may be sent if desired.
9.3.1.1.2 Q
Send the Q calculation result. The number send must be divided by 10 to
get the correct result. This command only operates in the SWR mode. No
EOS marker is required, but one may be sent if desired.
9.3.1.1.3 Mxx
Read the data stored in memory location xx. The EEPROM memory
location contains the unit setup info, and sometimes the plot from a single
sweep saved by the user. The maximum value of xx depends on the unit
version, and can be obtained using the S000 command. The number sent for
xx should always be a 2 digit number, for values less than 10 a leading zero
is required.
Location 00, last configuration used/power up default.
Locations 01 to 16, user defined instrument presets, no data.
Locations 17 to xx: presets and plot data.
This command requires no EOS marker, but one may be sent if desired.
9.3.1.1.4 S000
Read the unit's current setup. The entire setup is read in a fixed format
block of data. This command requires no EOS marker, but one may be sent
if desired.
9.3.1.2 Data Request Responses
9.3.1.2.1 Measured Data Response (R)
The unit response to an 'R' command will send a common header
followed by a block of data, the contents of the data are determined by the
instrument state established by the keypad or previous setup commands.
