Hi,
I've been testing SCPI commands via the Talker/Listener tab of the web interface with marginal success. However, I reloaded the web page after a response timed out, and now am being asked for a password to access the page. I haven't set a password, and basic guesses of what the default password might be (empty password, "Tektronix", admin, 0s, etc.) have all failed. Can you shed some light on why this is happening, and how to get around it? I've confirmed that I'm still connected to the device; the max delay between last successful SCPI command (DATA:STOP 1000) and lockout is maybe 2 minutes, and nothing has really changed.
