Inverse Assembler
With some skill, you can create an inverse assembler for the 16500 series. The package to do so is still on the Agilent website:
10391B Inverse Assembler
Problem is that the download (IALDOWN.EXE) tool with the kit is no longer usable on the fast desktops of today. Until....
I found DOSBOX
It allows old games to be played on windows - and Linux environments.
Tweaking the config to allow serial port emulation
[serial]
# serial1: set type of device connected to com port.
# Can be disabled, dummy, modem, nullmodem, directserial.
# Additional parameters must be in the same line in the form of
# parameter:value. Parameter for all types is irq.
# for directserial: realport (required), rxdelay (optional).
# (realport:COM1 realport:ttyS0).
# for modem: listenport (optional).
# for nullmodem: server, rxdelay, txdelay, telnet, usedtr,
# transparent, port, inhsocket (all optional).
# Example: serial1=modem listenport:5000
# Possible values: dummy, disabled, modem, nullmodem, directserial.
# serial2: see serial1
# Possible values: dummy, disabled, modem, nullmodem, directserial.
# serial3: see serial1
# Possible values: dummy, disabled, modem, nullmodem, directserial.
# serial4: see serial1
# Possible values: dummy, disabled, modem, nullmodem, directserial.
serial1=directserial realport:COM1
serial2=directserial realport:COM2
serial3=disabled
serial4=disabled
And... IALDOWN WORKED!
I'm looking at a way though to create a tool which takes a .R file, and creates directly a LIF header formatted file for the 16500B / C Logic analyzers. I don't think I can for the 16500A - as that analyzer does not support DOS formatted disks, so the 16500A will need to use IALDOWN... But now you can!
