«TL Len»
Sets the length of a transmission line, see section 4.1
«Marker»
Marker operations, see 2.6
3.3 Single Frequency Mode
The Single Frequency mode shows various fundamental parameters of a device under test at a
single frequency. These parameters comprise SWR, return loss (RL), magnitude (|Z|) and phase
(<Z) of the impedance, magnitude (|Rh) and phase (<Rh) of the reflection coefficient, resistance
(Rs) and reactance (Xs), and corresponding values of the capacitance (CS) and inductance (LS)
at the selected frequency.
The Run/Hold [ ] button controls the run status. The measurements can be stopped at any time
by pressing the Run/Hold [ ] button and resuming them by pressing this button again.
Functions
«Center»
Sets the frequency, see section 2.3
«Preset»
Sets the frequency using a preset, see section 2.4
«TL Len»
Sets the length of a transmission line, see section 4.1
«Audio»
Disables or enables VSWR audio feedback. When enabled the analyzer
produces beeps of different duration as an indication of VSWR. The duration of
the beep diminishes when decreasing the VSWR. The audio is produced only
for VSWR values between 1.0 and 10.0.
«Log»
