Right Plot Scale
Select the scale of the right plot. Choices vary depending on what is being plotted.
3.11 F5 Memory and Miscellaneous
This menu lets you save and recall data, set the plot name, set the cable properties, set
the baud rate, and perform a self test.
3.11.1
Save Operation
Instrument states and /or data may be saved in EEprom 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 is in 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 Impedance
You set the cable Zo 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
Zo is used for SWR calculations. The velocity factor is used in cable length calculations.
