address and volume number.
The following examples are for
an HP 9122 or HP 9133 floppy
disk drive set to HP-IB address 0:
GET“DOWNLOAD:CS80,700,1”
or
GET “DOWNLOAD:,700,1”
If you are not getting the
program from a floppy disk,
skip the “:,700,1” portion of the
filename, but include the full
path name for the file. The MSI
command could be used to set
the HP BASIC environment to
the correct directory.
After loading the program, press
the RUN softkey or type RUN,
followed by the return key.
The program will prompt you
for the file name to download. In
keeping with the above example
using a floppy disk, you would
type:
G_DEL_IB:,700,1
You should see the program
lines displayed on the screen as
the program is being
downloaded to the HP 71500A.
This process will take a few
minutes to complete. At the end
of the download process, the
program will ask you if you want
to store the program to the
mainframe’s default drive. If you
have a formatted 128K RAM
memory card available, and the
default drive is set to MEMORY
CARD (select under the DISPLAY
keys: Mass Storage; msi),
then enter “Y” to store the
program. An alternate way to
store the program to a memory
card is described in the next
section, along with details of
how to format a memory card.
If you are working in a UNIX
®
environment, it is possible to
download the program directly
from the hard disk drive using a
script program, without having
to run HP BASIC or use a
floppy disk. This method is
much faster than using the HP
BASIC download program.
Storing to a memory card
Once the group delay program
has been downloaded to the
instrument, it can then be stored
to a memory card. A 128K RAM
memory card (HP 82215A)
should be used.
Note: the memory card uses a
CR2016 lithium battery. It is
recommended that the battery
be changed annually. To retain
the data stored on the card, the
battery should be replaced
while the card is installed in the
mainframe with the power on.
The memory card must be
formatted before it can be used.
To format a new card, press the
MENU key below the display,
followed by mass storage
(more 2 of 2) under the
States menu (page 2 of 2).
Next, press more followed by
FORMAT. You can select either
DOS or LIF format. After the
formatting is compete, press the
USER key to activate the
IBASIC keys. To save a program
on the card, simply type:
SAVE “G_DEL_IB”
involves using an external
computer, and the other uses
the mass storage capability of
the HP 70004A color
display/mainframe. The latter
method can load the program
either from a floppy disk or a
memory card. Since the
program is likely to be supplied
on a floppy disk, it is desirable
to copy it to a memory card as
soon as possible. Subsequent
downloadings can then be done
from the memory card, which
alleviates the need to have an
external computer or floppy
disk drive.
Loading from an external
computer
The most common way of
downloading the program with
an external computer is to use a
floppy disk. Alternately, the
program can be downloaded
directly from the computer’s
hard disk drive. This is useful if
the program was obtained via
e-mail or ftp. Several choices
for computers exist, such as an
HP 9000 series 300 running
HP BASIC/WS, an HP 9000
series 300/400/700 running
HP-UX (with HP BASIC/UX
running as an application), or a
personal computer (PC) running
HP BASIC/DOS. The computer
must have an IEEE-488 (HP-IB)
port to communicate with the
HP 70004A mainframe.
From the HP BASIC operating
environment, load and run the
ASCII program DOWNLOAD.
To load an ASCII file using HP
BASIC, use the GET command.
You may need to specify the
mass storage logical name,
