SMFP2 :
General Info
The mobile tester SMFP2
is a compact, integrated test sets for the entire range of AM, FM and QM transceiver
measurements. It is part of the famous SMFP(2) and SMFS(2) family of Rohde & Schwarz build
between 1980-1984. At that time their prices were around 40.000 USD.
The difference between the SMFP2 and SMFS2 is that the SMFP2 has a GPIB interface
(R&S called it IEC-bus) and a continuous tuning modulation generator (10 Hz to 25
Khz), while the SMFS2 has
no GPIB
interface and only 12 fixed frequencies.
The SMFP is an older version of the SMFP2,
also equiped with a GPIB interface and therefore suitable for automatic measurements.
A good second hand SMFP2 /SMFP will set you back around 600 - 900 Euro when fully operational.
Offers around 300 - 500 Euro will suffer from the usual deficiencies like faulty
LCD display, power supply and "smoky" ELCO's, but still can be a good catch.
However, watch out if it lacks some essential circuit boards because rebuilding
them will be costly, and some IC's are obsolete and hard to get. Getting exchange LCD's
is almost impossible.
