Loading the ENR Data from Diskette
Loading the ENR Data from Diskette
To load the ENR data from the diskette and use the data as the current
ENR table, proceed as follows:
Step 1. Power up the Noise Figure Analyzer and wait for the power-up sequence
to complete.
Step 2. Insert the diskette into the floppy drive of the Noise Figure Analyzer.
NOTE
Do not insert the diskette into the Noise Figure Analyzer until the
power-up sequence is complete.
Step 3. On the Noise Figure Analyzer, press the
File
key and press the
Load
menu key to access the file system.
Step 4. Press the
ENR
menu key and select whether the ENR table is a
Meas
Table
(used for measurements) or a
Cal Table
(used for calibration). If you
intend to use the same ENR table for calibration and measurement, then
set the ENR table as
Meas Table
.
The Noise Figure Analyzer allows you to use the same or separate ENR
tables for calibration and measurement as required. For more details on
specifying
Meas Table
and
Cal Table
, see the Noise Figure Analyzer User’s
Guide .
Step 5. Press the
Select
menu key and use the arrow keys if necessary to
highlight [-A-]. If
C:
is the currently selected drive use the
“..”
directory
to reach the
A:
drive as directed on the screen. Press the
Select
menu key
again to read the diskette.
Step 6. Use the down arrow key (
↓
) to highlight the ENR file and press the
Enter
key to load it.
When the file is successfully loaded a message, for example
A:A0100364.ENR file loaded
appears on the display.
Note that ENR files with a large number of frequency points (for
example, up to 50 GHz) may take a few seconds to load.
