Software CD-ROM for 2401

Hi, we purchased a Keithley 2401 not long ago, and there should be a CD-ROMs for software download coming with the package. We did not get that CD-ROMs, so we are hoping that we can get that resent to us or if there is any online links for us to download them. Thank you. 

Tek no longer provides CD-ROMs with our products. You can find all relevant downloads here:
