If you get the "Sorry, the file cannot be displayed. There seems to be a technical issue ..." error when trying to view an image, a workaround is to click on the cog icon in the upper right side of the media viewer, and then select "Disable Media Viewer". We are aware of the problem and are looking for a solution.

The Tektronix 7L5 is a low frequency (10 Hz – 5 MHz) spectrum analyzer plug-in for 7000-series scopes. It has built-in digital storage so it will work fine in non-storage mainframes, such as the large-screen 7603. It also features digital scale and marker level/frequency (6 digits) readout, and a "max hold" function. Instruments with a serial number below Β070000 are missing the B - (Save A) feature and the corresponding button on the front panel. The military version is called PL-1391/U and is also lacking the B - (Save A) feature.
