1. Restrictive protection: Specifies the highest input RF level and the highest voltage value causing permanent damage: DC 25V, AC peak-to-peak 100V.
2. Warm up: The test must wait until OVERCOLD disappears.
3. Self-education: Self-study for three months or important measurements.
4. System Measurement Configuration: The configuration is to input some parameters of the measurement before measurement, and to save one parameter input for each measurement.
Content: Test items, signal input method (frequency or channel), display unit, system, noise measurement bandwidth and sampling point, CTB, CSO frequency, test line strobe, etc.
Configuration steps: Press the MODE key - CABLE TVANALYZER soft key - Setup soft key to enter the setting state.
Details tuneconfig tuning configuration: including frequency, channel, system, level units. Analyzerinput input configuration: whether to add a preamplifier. Beatssetup beat frequency, CTB, CSO frequency points (frequency offset CTBFRQoffset, CSOFRQoffset). GATINGYESNO gated test line. C/Nsetup C/N ratio setting: frequency point (frequency offset C/NFRQoffset), bandwidth.
Before any instrument can be used normally, it must be tested. Of course, the spectrum analyzer is no exception. Friends who often deal with the analyzer know how to prepare for testing? The experts of Instrument World World Network below will tell you how to prepare for the test.
