General Information
Introduction
Standard Data Format Utilities is a group of MS-DOS®programs for doing the
following things (see figure 1-1, on the following page):
• Converting files between LIF format and DOS format.
• Sharing data between HP DSA analyzers.
• Displaying analyzer data on your PC.
• Reading data from files into a program.
(MS-DOS is a U.S. registered trademark of Microsoft Corporation)

Figure 1-1. Data Exchange Capabilities
General Information
Notice in figure 1-1 that the data from some analyzers, such as the HP 3563A, must be converted first
from LIF to DOS, then to SDF format. For some other analyzers, such as the HP 3566A, no conversions
are necessary—these analysers save data in SDF format directly.
The Standard Data Format Utilities support saved data from the following DSA analyzers:
• HP 35665A (to and from)
• HP 35670A (to and from)
• HP 3562A (to and from)
• HP 3563A (to and from)
• HP 3566A/3567A (to and from)
• HP 35660A (from only)
• HP 3560A (from only)
• HP 3569A (from only)
• HP 3588A (from only)
• HP 3589A (from only)
• HP 89410A/HP89440A (to and from)
• HP 3587S (time capture files only)
There are some limitations on data exchange. For example, order tracking data from an
HP 3567A cannot be post-processed in an HP 3563A because the HP 3563A does not do
order tracking measurements.
The Standard Data Format Utilities also allow you to translate data files to the following formats
compatible with third party software:
• PC-MATLAB, a trademark of The MathWorks, I nc., is a software package for general digital
signal processing and filtering.
• MATRIXx, a product of Integrated Systems Inc., is a software package for control
system analysis.
• Data Set 58 is the universal ASCII format for mechanical test.
• ASCII is a versatile format for spreadsheets and other general software.
Programs that convert from Standard Data Format to SMS formats are available from SMS for use with
the following application software:
• STARModal, a trademark of SMS, is a software package for doing modal analysis of structures,
including structural modification and force/response analysis.
• STARAcoustics, a trademark of SMS, is an acoustics software package with 1/3 octave, sound
intensity, and sound power analysis.

Converting Files Between LIF Format and DOS Format
Converting Files Between LIF Format and DOS Format
LIF (Logical Interchange Format) is the Hewlett-Packard standard disk format that may be used to
exchange files among various HP computer systems and instruments. The LIF programs in the Standard
Data Format Utilities make it possible for personal computer users to translate LIF files into DOS file
format, and DOS files into LIF format. The utilities support file conversion for both internal drives and
external drives connected on the HP-IB. These utilities can also format and initialize LIF disks on
external HP drives.

General Information
Data Sharing Between Analyzers
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.
Cable # HP24542G to 25 pin RS232
HP 24542U to 9-pin RS 232
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.)
1-5
General Information
Data Sharing Between Analyzers
You can compare old data from an HP 3562A to new data from an HP 35665A, as shown in figure 1-3.
You can convert the HP 3562A data from LIF to DOS, then from HP 3562A format into SDF, then recall
it into an HP 35665A for comparison. Or you can convert HP 35665A data from SDF format to
HP 3562A format, then convert it from LIF to DOS, then recall it into an HP 3562A for comparison.
Figure 1-3. HP 3562A to HP 35665A
Batch Files
Appendix C contains several example batch files. These are ‘’automated’’ procedures that combine two
or three utilities. For example, ‘’63_SDF.BAT’’ performs the LIF-to-DOS conversion and the
HP 3563A-to-SDF conversion on a group of files. You can use the existing batch files, or you can copy
and modify them for your particular needs.

Displaying Analyzer Data on a Personal Computer
Displaying Analyzer Data on a Personal Computer
The Viewdata utility allows you to display data graphically on your PC. You can display up to
three traces of data from the same or different analyzers. For example, you can display a frequency
response from an HP 3563A on trace A, a frequency response from an HP 35665A on trace B, and
a frequency response from an HP 3566A/3567A on trace C. Chapter 5 describes the Viewdata utility in
detail.
Note You must convert HP 3563A/62A data from LIF to DOS before reading it into
Viewdata. See chapter 3.
The utility includes marker, scale, zoom, and scroll functions. You can also plot or print the display to
HP-GL plotters or PCL printers (for example, the HP LaserJet or DeskJet).

What is Standard Data Format?
Introduction
Standard Data Format, SDF, is a data format that allows measurement and analysis data to be shared
among several HP analyzers (see chapter 1 for a list of the supported analyzers). See appendix B for a
complete description of each field in the SDF file.
SDF supports analyzers with a very broad range of functionality. Not all the supported analyzers use
SDF’s full capabilities. The rest of this chapter describes some of these differences. Use the SDFTOSDF
utility (described in chapter 4) to extract from an SDF file the information of interest.
2-1
What is Standard Data Format?
Measurement (Data) Results
Measurement (Data) Results
Some analyzers save a complete set of measurement results. Others save an individual trace.
For example, when you save data from an HP 3566A/67A frequency response measurement, the file
includes five measurement results (or measurement data): FRF, coherence, input power, output power,
and cross power. When you save data from an HP 35665A FFT measurement, the file includes only the
measurement data displayed in the active trace. In the SDF file, these are called ‘’data results.’’
Figure2-1. DataResults
If you want to recall FRF data from an HP 3566A/67A into an HP 35665A, use SDFTOSDF /D to select
the measurement data of interest from the HP 3566A/67A data. See the SDFTOSDF command in chapter
4 for more information.
The HP 35665A can read HP 3566A/67A data directly into the instrument, but it can read only the first
trace in the file with:
• 1st data result
• 1st row
• 1st column
From the HP 3566A/67A, the save trace command can be used to save a specific trace to disk.
2-2
What is Standard Data Format?
Number of Input Channels (Rows)
Number of Input Channels (Rows)
Another difference between SDF files is the number of input channels. For example, the HP 3566A and
HP 3567A are multi-channel analyzers with up to 16 input channels, and the other supported analyzers
have only one or two input channels. In the SDF file, these are called ‘’rows.’’
Figure 2-2. Rows
If you want to recall FRF data from an HP 3566A/67A into an HP 35665A, use SDFTOSDF /R to select
the HP 3566A/67A channel combination (row) of interest. See the SDFTOSDF command in chapter 4
for more information.
2-3
What is Standard Data Format?
Waterfalls and Maps (Scans)
Waterfalls and Maps (Scans)
Some of the supported analyzers allow you to save waterfalls or maps—a number of spectra. These may
be the waterfall steps for an HP 35665A measurement or map lines for an HP 3566A/67A
rpm spectral map, for example. In the SDF file, these are called ‘’scans.’’
Figure 2-3. Waterfall or Map Scans
Use SDFTOSDF /S to select the scan (map line or waterfall step) of interest. See the SDFTOSDF
command in chapter 4 for more information.
2-4
What is Standard Data Format?
Time Capture (Scans)
Time Capture (Scans)
Some of the supported analyzers allow you to capture long streams of raw time data and then later replay
the data into a measurement in the instrument. The HP 3566A/3567A, HP 35665A, HP 35670A,
HP 89410A, HP 89440A, and HP 3587S support this capability. The time data in the file is broken up
into scans in the same manner as with waterfalls and maps (see the preceding section). The scan size is
determined by the instrument and is generally related to the number of time points the instrument uses to
generate an FFT in its current measurement.
Figure 2-4. Time Capture Scans
Time Channel and Frequency Correction are generated by all instruments. Overloads are generated by
the HP 3566A/3567A only. Compressed Time, Tach Data, and External Trigger Data are generated by
the HP 3566A/3567A and the HP 35670A.
See Appendix B for more information on Time Capture Files.

File System Conversion (LIF/DOS)
Description
LIF (Logical Interchange Format) is the Hewlett-Packard standard disk format that may be used to
exchange files among various HP computer systems and instruments. The LIF programs in the Standard
Data Format Utilities make it possible for personal computer users to translate LIF files into DOS file
format, and DOS files into LIF format. The utilities support file conversion for both internal drives and
external drives (connected on the HP-IB). These utilities can also format and initialize LIF disks on
external HP drives.
The LIF utilities consist of the following commands:
LIF Main program for LIF access. The first parameter specifies the function (e.g.,
SCAN or CHK). Each function has its own options. These options are documented
later in this chapter.
3
LIF SCAN Checks the PC for internal floppy drives and for HP-IB interface boards and then
looks for disk drives (capable of reading LIF disks) connected to HP-IB.
LIF CHK Verifies that the disk inserted in a designated drive is fully readable by the LIF
Utilities. (To abort, type:
LIF LS Lists the contents of the LIF directory.
LIF C P Copies a LIF file to a DOS file, a DOS file to a LIF file, or a LIF file to another LIF
file.
LIF R M Deletes a specified file from the LIF directory.
LIF INIT Optionally formats and initializes a new directory on a LIF disk. (To abort,
type:
CTRL-C.)
LIFDIAG Diagnostic utility useful for performing fast LIF to LIF full disk backups and for
recovering data from damaged/corrupted disks.
CTRL-C.)
3-1
File System Conversion (LIF/DOS)
Hardware and Software Requirements
Hardware and Software Requirements
Use of these utilities requires an IBM PC compatible with the MS-DOS 2.1 operating system (or greater).
If you wish to translate or format LIF files located on an external drive you must have an SS/80 drive
connected to your PC with an HP-IB card. The LIF utilities recognize all HP SS/80 drives including the
HP 9122, HP 9133 (D,H,L), HP 9127A and HP 9153A. Older disk drives (AMIGO command set) such
as the HP 9121, HP 9133 (V, X, or XV) will not work. (SS/80 disks are a subset of HP CS/80 disks.)
There are no requirements for internal disk drives.
The HP 88500A and HP 82335 HP-IB cards, as well as the National GPIB PCII and AT-GPIB cards are
recognized. Make sure that your HP-IB (or GPIB) is set to System Controller, the default switch setting.
Caution Disk cache programs may interfere with the LIF utilities access to the
internal floppy disk drives and may cause disk read errors or program lockup.
We recommend that disk cache programs not be used in conjunction with
these utilities.
You can use the SMARTDrive disk caching software provided with Microsoft Windows
3.0.
Note The utilities will work with both an HP and a National card installed simultaneously.
For example, you can LIF copy files from a disk drive on the HP card to a disk drive on
the National Instrument card.
Both BDAT and ASCII LIF files may be converted to DOS. (Binary LIF files are copied in
raw mode.)
