Anritsu FAQs

On my MS272xC it seems to take a very long time for the GPS to lock. Is there anything that can be done to improve it?
answer

Yes. Change the default GPS voltage from 3.3 Volts to 5 Volts. The default output voltage that powers the preamplifier in the GPS antenna is set to 3.3 volts to avoid the possibility of damaging an antenna that needs that voltage. However, the antennas sold with the MS272xC are designed to run on 5 volts. You can choose which voltage the instrument puts out by pressing | Shift | System | GPS| and making sure that 5 volts is underlined.
