Operating Instructions
Display settings
Turn on-screen display items on or off using the soft-menu buttons to show or remove a
variable. For some items, pressing the button once shows the display item and pressing it
again hides the item. Asterisks (on the menu) will appear on the sides of displayed items.
Some items may disappear automatically when scanned traces are selected.
Show Ohms/rho
This item toggles on or off the impedance display in Ohms and the reflectance display in
millirho.
Show date/time
This item toggles the date and the time display on or off. The first setting shows both
the time and date, the next shows only the time, the next shows only the date, and the
last turns the on-screen display of date and time off.
Show distance
This item toggles showing the distance measurements including meters (or feet) and
nanoseconds.
Show VSWR
This item toggles the VSWR and RVSWR displays on or off.
Change screen profile
This item switches between white, black, and slate grey color schemes.
Horiz./vert. ruler
This item toggles the horizontal and vertical measurement rulers on and off. The rulers
make judging trace values simpler, but also take up a lot of screen area.
Noise value
This items toggles the display of a noise measurement. This is rarely needed except for
troubleshooting and calibration checks.
Show scale values
This item toggles the horizontal and vertical scales on and off.
Show cursor/trace intersection
This item toggles an 'x' crosshair where the vertical cursor intersects the on-screen
trace.
Show absolute/relative return loss (Decibels)
This item toggles the display of relative return loss at cursor.
Show temperature
This item toggles the temperature displays on and off. These temperatures are
accurately measured on the (internal) analog board as a calibration reference. It also
serves to display to the user when the device may be running at potentially high
temperatures on critically sensitive electronic components.
