PROGRAMMING THE UNIT
Three steps are necessary:
v Upload values from the unit
v Edit the values
v Download values to the unit
Uploading Current Unit Settings (F5)
First, you must read into the computer what is in the unit’s memory at present. To do this,
press F5. The data replaces the default on the screen.
v The program insists that you do this before allowing you to reprogram the
unit to make it less likely that inappropriate values be entered.
v However, once you have uploaded during a session, you may edit and
download the data to as many units as you wish.
Caution: If you do this, you must ensure that the units are all of the same
type. Check that all units are of the 13MHz TCXO type (“13MHz TCXO”
label affixed opposite serial number label) or the 12.8MHz TCXO type (no
such label). If you change unit type, you must use F5 again.
Programming Individual Channels (0-15)
To set the frequency of one of the first 16 channels (0-15), which can be individually set,
use the arrow keys to move the highlight over that channel and type in a frequency in
MHz.
v The entered value must be an integer multiple of the Comparison Frequency
shown at the top right of the screen, otherwise an ‘invalid’ message is
displayed.
v Make sure that the value is within the switching bandwidth of your unit, as
the software cannot prevent you from inserting an inappropriate value.
Press the <enter> key to complete.
Programming Sequential (Table or Block) Channels (16-127)
To set the frequency of channels 16-127, which can only be allocated as a block, use the
arrows to highlight Start Table and type in the lowest frequency (channel 16).
v The entered value must be an integer multiple of the Comparison Frequency
shown at the top right of the screen, otherwise an ‘invalid’ message is
displayed.
