DADiSP / ISF 1.1
Tektronix Instrument Specific File
The Tektronix Instrument Specific File, ISF, stores channel
data from a GPIB instrument in the same format as the instrument
responds to a remote GPIB
command. The ISF data
stream consists of an ASCII preamble followed by the raw binary
data. The preamble contains information regarding the sample rate,
units and scaling parameters used to convert the raw data to real
For example, a typical ISF data stream might appear as:
:WFMPRE:BYT_NR 2;BIT_NR 16;ENCDG BIN;BN_FMT RI;BYT_OR MSB;NR_PT 10000;WFID "Ch1, DC coupling, 2.0E0 V/div, 1.0E-5 s/div, 10000 points, Sample mode";PT_FMT Y;XINCR 1.0E-8;PT_OFF 0;XZERO 3.5E-4;XUNIT "s";YMULT 3.125E-4;YZERO 0.0E0;YOFF 0.0E0;YUNIT "V";:CURVE #520000
DADiSP/ISF automatically processes the preamble to produce
scaled engineering data with the proper sample rate and units.
Single byte and 2-byte raw integer data in signed and unsigned
formats are supported. A wide range of Tektronix instruments produce
ISF files including MSO4000, DPO4000, MSO3000, DPO3000, MSO2000,
DPO2000, TDS3000, TDS3000B, TDS3000C Series oscilloscopes.
Simple Menu Interface
DADiSP/ISF runs from the DADiSP worksheet and is accessed
by a press of a button. The ISF user interface displays
important file information and supports both raw data
transfer and appropriately scaled engineering values. The data
is converted directly and efficiently, with no need to rely on intermediate
TXT or CSV formats.
Full Analysis System
DADiSP provides a complete analysis, display, and processing
environment using ISF data. The integration of
DADiSP/ISF into DADiSP makes it easy to automate data import
and analysis applications completely through SPL (Series Processing
Language), macros, and command files.
DADiSP/ISF requires DADiSP 6.5 B05
for information about updating your current
version of DADiSP.
