Tektronix TDS 540 and options
I've got TDS540 oscilloscope that originally came without
RS232/Centronix interface. Later on I was able to salvage interface module from a dead TDS540 hoping to be able to capture waveforms on my computer and that's where the fun begins. When oscilloscope powers up with RS232 module installed, it shows diagnostics page with all tests marked as 'pass' and a message that there was hardware configuration mismatch and one should check error log. Checking error log reveals that the 'scope is unhappy about finding rs232 module while its records tell that there should be none. I wonder if anybody knows how to change configuration of TDS540 oscilloscope so it would recognize it properly? On a side note, would anyone happen to have firmware upgrade for TDS5xx family oscilloscopes (or 6xx or 7xx)? Upgrade procedure is described in the service and user manuals but so far I did not manage to find the firmware. My oscilloscope is from one of the earlier batches, according to its serial number and has f/w v1.10e. I've seen newer firmware on other scopes (v2.*). Thanks, --Artem |
