Polarity.
13 on the meter is Vertical (or RH if you are using circular)
18 on the meter is Horizontal (or LH if you are using circular)
LO stands for Local Oscillator.
It is the oscillator used by your LNB or LNBF. It MUST match in your meter, so enter the same LO information
from your LNB into your meter in the 'LO' field. Most LNBs have the LO printed on the label.
Common LO's are:
• Universal LNBF: 09750 & 10600
• US LNBF: 10750
• DSS LNBF: 11250
LNBFs with 2 LOs use 22 KHz for switch between them.
22KHz is used to switch between LO's on 2 LO (universal) LNBFs. Take a look at any spec sheet and it
should tell you the LO frequencies and the output frequency. For example see the spec sheet on the famous
Spitfire Elite LNBF. You will see the low band LO is 9.75 GHz and it covers 10.7 to 11.7 GHz. The high band
LO is 10.6 GHz and it covers 11.7 to 12.75 GHz. So, the transponder frequency you are looking for determines

which LO you should use.
When the 22KHz is blank it is OFF and selecting the low band frequency, 10.7 to 11.7 GHz (10700 to 11700
Mhz).
When the 22KHz is ON it is selecting the high band frequency, 11.7 to 12.75 GHz (11700 to 12750 MHz).
In the USA the common frequency range is 11.7 to 12.2 GHz. If you are using a universal LNBF, set the LO to
10600 and the 22KHz to ON.
So, the rule of thumb for universal LNBFs is; 22KHz OFF selects LO 09750. 22KHz ON selects LO 10600.
