3.11.1 Save Operation
Instrument states and data may be saved in EE-prom for recalling at a later time. There
are two types of save memories. The first type only saves instrument presets; the other
saves both the presets and the plot data. One can use the preset only memory to save
instrument states for a number of different antennae. The full data save could record the
impedance of an antenna then transfer it to a PC for further analysis or to save history
information.
3.11.1.1 Instrument Presets
Memory locations 1 through 16 save the instrument presets only.
3.11.1.2 Plot Data
Memory locations 17 to 24 save both plot data and instrument presets.
3.11.2 Recall Operation
Memory recall is the compliment to memory save. When memory locations 17 to 24 are
recalled, the saved data is displayed, and the unit changes to the exam mode, allowing you
to view the data and move the cursor across it. Once you leave the exam mode the display
is updated with new data, but the saved data is still intact in the save memory slot, ready to
be recalled again if necessary.
3.11.3 Plot Name
Allows you to assign up to a 12 character name to the save data. A descriptive name will
help you remember what the plots are when downloading the data to a PC. You can enter
the name via this submenu, or you can enter it during the save operation.
3.11.4 Cable Properties
You set the cable Z
0
and velocity factor in this sub menu. Operation is similar to
frequency, you my need to enter zeroes to align the velocity factor to the decimal point. The
Z
0
is used for SWR and cable nulling calculations. The velocity factor is not used for any VIA
Bravo MRI calculations.
3.11.5 Com Port Baud
You can set the baud rate you wish to use in this sub menu. The data format is always
N-8-1 with XON/XOFF handshaking.
3.11.6 Self Test
You can perform a self test by selecting this choice. Press Enter to exit the self test.
Pressing any other key creates a response that indicates the key is operating.
