    The TR501 Tracking Generator is designed for use with the 7L12

    Resolution bandwidth can be varied from 300 Hz to 3 MHz, with -115 dBm sensitivity at 300 Hz. Automatic phase lock results in good stability.
    The 7L12 meets the measurement requirements of many AM, FM, two-way radio and other communicatiosn systems.
    The 7L12 has a 70 dB spurious-free display dynamic range; low level noise measurements are made accurately, easily.

    ---------------------------------------------------------------------
    The 7l12 analyzer manual specifications are; displays frequencies from .1 MHz to 1.8 Ghz (microwave), frequency steps are in 1-2-5 sequence from 500/div to 100 MHz/div. The display modes are Log 10 Db/div, Log 2Db/div, Lin, Reference level is from -100 Dbm to +30 Dbm, featuring CRT Readout of center frequency Resolution Bandwidth from 300 Hz to 3 MHz and Automatic Phase locking. This unit has SMA connectors for a tracking generator connection to the LO1 and LO2 oscillators and the newer LED readout of the reference level. This TEK analyzer unit has an advantage over the wider 7l13 units as it takes up only 2 slots in your scope rather than 3 with the 7L13 leaving some room for additional plugins and the SMA LO connections allow connection of a variety of tracking generators. This unit is complete with all knobs and controls . The 7l12 analyzer displays frequencies from .1 MHz to 1.8 Ghz (microwave) and but does not have digital storage like the 7L5, 7L14 and 7L18 featured. This Tek analyzer of this well proven brand has a variety of uses regarding RF transmission or radio frequency communication from test, troubleshooting and repair to research, to analyzing TV or satellite signals.
