7L13: Difference between revisions

Revision as of 08:53, 8 February 2021

The Tektronix 7L13 is a 1 kHz to 1.8 GHz Spectrum Analyzer plug-in for 7000-series scopes.

It is similar to the 7L12 but occupies three module bays, adds a marker function, offers resolution bandwidth down to 30 Hz, and improves sensitivity by 10 dB. It also displays the center frequency in the CRT readout as well as on a LED display.

The TR502 tracking generator is designed to work with the 7L13 up to 1.8 GHz.
