GSM ORFS Measurement - RF Cafe Forums

The original RF Cafe Forums were shut down in late 2012 due to maintenance issues - primarily having to spend time purging garbage posts from the board. At some point I might start the RF Cafe Forums again if the phpBB software gets better at filtering spam.

Below are the old forum threads, including responses to the original posts.

Hi,
When measuring GSM ORFS using any test instrument as Agilent 8960 or a spectrum analyzer, the measurement result is always at discrete frequencies.
I.e. the result is given in specific frequency offsets: Carrier +/-200KHz, +/-400KHz etc. Even at graph representation, between those offsets there is no information.
Why isn't the measurement continiuos, Even though the spectral energy is at all frequencies? In addition why those specific frequencies were choosen?
Tnx

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a lady's voice announced "You've Got Mail" when a new message arrived...
