TR4120A

The TR4120A is a tracking scope having the following performance:
Measurement range: 100 Hz to 30 MHz
Resolution: Max. 10 Hz
Input sensitivity: Max. -135 dBv
Dynamic range: 80 dB

Fuerthermore, since TR4120A includes a tracking generator, it directly reads and analyzers the frequencycharacteristics in addition to analyzing the spectrum. Also, connecting an ADVANTEST frequency counter to this device provides a function to read the frequency on the marker point at an accuracy specified by the frequency counter.

This tracking generator is operated as a selecive amplifier (or tuned amplifier). Using this function, some weak signal is selected and amplified. The ON-AIR signal can be measured at an accuracy specified by the carrier frequency counter.
