With power applied (power knob pulled out), the spectrum analyzer will automatically (upon microcomputer control) go into the following conditions. If you do not find these indications, there is a probably a problem with the unit.

·   Vertical display: 10 dB/div;


·   Frequency: 0.00 MHz;

·   REF level: +30 dB;


·   RF attenuation: 60 dB;

·   Frequency range: 0.0 to 1.8 GHz;

·   Auto resolution: 1 MHz;


·   Resolution bandwidth: 1 MHz;

·   Freq Span/Div: Max;

·   Triggering: Free run;

·   Readout: On;

·   Digital storage: View A/View B On;




·   All other indicators off or inactive.




Now that we have completed this chapter, we will briefly review the more important points covered. a CATHODE-RAY TUBE (CRT) is used in an oscilloscope to display the waveforms.

The CRT used in oscilloscopes consists of an ELECTRON GUN, a DEFLECTION System, and a FLUORESCENT SCREEN.


The ELECTRON BEAM in an oscilloscope is allowed to be controlled in any direction by means of HORIZONTAL- and VERTICAL-DEFLECTION PLATES.


VERTICAL-DEFLECTION PLATES are used to show Amplitude of a signal.


HORIZONTAL-DEFLECTION PLATES are used to show TIME and/or Frequency



A GRATICULE is a calibrated scale of Amplitude VERSUS TIME that is placed on the face of the CRT.


A DUAL-TRACE OSCILLOSCOPE is designed to accept two vertical inputs at the same time. It uses a single beam of electrons shared by two channels.


The SPECTRUM ANALYZER accepts an electrical input signal and displays the signal's frequency and amplitude on a CRT display.


Answers to Questions Q1. Through Q18.


A-1.   Control grid.


A-2.   The first anode.


A-3.   Because they bend electron streams in much the same manner that optical lenses bend light rays.


A-4.   It accelerates the electrons emerging from the first anode.


A-5.   a greater deflection angle.


A-6.   a greater deflection angle.


A-7.   Higher potential.


A-8.   Slower beam.


A-9.   Amplitude and time.


A-10.   Amplitude.


A-11.   Time and/or frequency relationships.




A-12.   To permit wide-angle deflection of the beam.


A-13.   Deflection factor.


A-14.   a CRT, a group of control circuits, power supply, sweep circuitry, and deflection circuitry.


A-15.   Lower.


A-16.   Amplitude, phase, time, and frequency.


A-17.   Dual-trace oscilloscopes.


A-18.   Front end.

About RF Cafe

Kirt Blattenberger - RF Cafe Webmaster

Copyright: 1996 - 2024


    Kirt Blattenberger,


RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...
