Data Sharing Between Analyzers
These utilities make it possible to take data with one analyzer and recall it into another analyzer for
post-processing. (Chapter 4 describes these utilities in detail.) For example, you can make a frequency
response measurement with an HP 3560A, transfer the data to your PC, convert it to SDF format, then
recall it into an HP 35665A for curve fitting.
Figure 1-2. HP 3560A to HP 35665A
To connect the HP 3560A or HP 3560A to the PC: use Cable #HP 24542G to 25-pin RS-232 or Cable
#HP 24542U to 9-pin RS-232. For more information on the cables required to connect the HP 3560A to
the PC, refer to the chapter ‘’Transferring Data to a Personal Computer’’ in the HP 3560A Quick Start
Guide.
Some analyzers only accept data with 401 frequency lines, others accept only 801 frequency
lines, and others allow you to specify more or fewer frequency lines. The SDFTOSDF utility
(see chapter 4) allows you to convert data from one number of frequency lines to another. For example, if
your HP 3560A or HP 3569A measurement was done with 1601 lines, you must convert it to 801 lines
before you can curve fit it in an HP 3563A, using the command
SDFTOSDF /P:801. (Although the
HP 35665A can only create 401 line data, it can display and curve fit data with
801 lines.)
