4.6.2. Practice
Press
+ to open Impulse Response (IR) and Step Response (SR) graphs:
The characteristic impedance and the velocity factor of the cable, as well as display
units (meters or feet) may be changed in the Settings menu.
The
(ok) key starts a new measurement, which will take about a minute. You may
disconnect your antenna or leave it connected to the far end of the cable. This will only
affect the part of the graph located behind the far end of the cable.
Use the arrow keys to move the cursor or to change the display range. Watch the
navigation bar at the top-right corner of the screen to see the current position of the
displayed part of the graph.
The
key will start a new measurement, saving results in one of 10 memory
slots. The key will retrieve saved data. Use the
+
combination to edit
memory names, if needed.
Pressing
+
opens a data screen which displays numerical values of impulse and
step response coefficients, as well as Z (estimated impedance) at cursor.
The
key will display the help screen, as usual.
