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. According to the 070-2184-01 manual 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.
