2200 / 2240 / 2241 PathAlign-R Manual
1-5
The PathAlign-R provides a switch-selectable 'Alignment Tone' on the front panel that functions
as an audible path loss indicator. This variable-pitch tone is inversely proportional to the path
loss of the link (low tone/greatest path loss; high tone/least path loss). The pitch of the tone
ranges from approximately 600 Hz to 5 kHz (3-octaves), for a proportional path loss -100 dBm
to -30 dBm (the dynamic range of the PathAlign-R). In other words, as the link alignment
improves, the tone rises.
The rear panel contains the battery access door allowing for removal or replacement of the
internal battery. A rear panel BNC connector outputs 0-2VDC,relative to the front panel meter
reading for providing remote reading of path loss (1mV=0.1dB). A rear jack (5.5mm x 2.1mm)
allows connection of the Battery Charger for charging the internal battery.
(Note: Use only the
Battery Charger supplied with the PathAlign-R, another charger may damage the
PathAlign-R or the battery!)
. If the charger is lost or damaged a replacement may be
purchased from Spectracom.
The Record-R Data Logger found in models 2241/2241A allows the user to record and store an
individual data record in the instrument's memory with the push of a button. The memory used
for this storage is non-volatile; it is not affected by turning of instrument off. The Data Logger
also contains an imbedded GPS receiver to provide location/date/time information to the record.
The information stored included the instrument's model number (e.g. 2241), serial number, date
and time, location (latitude and longitude), frequency in use and the measured path loss. Up to
250 individual records can be stored in memory.
Included with the Record-R is a software utility called the LogView-R which allows connection to
a PC computer running Windows, via RS-232 or USB, for downloading, viewing, saving to disk
and printing of the records stored, as well as clearing the instruments memory.
