SWR Meter Manufacturer,Supplier and Exporter in India
Product Code : EL-M-10465
Jlab Export is a leading SWR Meter Manufacturer,and suppliers in India
SWR Meter (code EL-M-10465) is a microcontroller-based meter that shows the standing wave ratio (SWR) and its value in dB on a digital LCD, in place of the several scales of an analog meter. Students read the result directly, with no expanded scales to choose between. This digital SWR meter is made by JLab in Ambala, India.

What the SWR Figure Means
When a line feeds a load that does not match it, part of the signal is reflected and a standing wave forms along the line; SWR is the ratio of its maximum to its minimum voltage. It follows from the magnitude of the reflection coefficient Γ: SWR = (1 + |Γ|) / (1 − |Γ|), where |Γ| = √(reflected power ÷ forward power). A perfectly matched load reflects nothing and gives an SWR of 1, and the figure climbs as the mismatch grows.
Why a Digital Readout Suits Student Labs
A conventional analog SWR meter carries several scales, often with expanded scales as well, so students can be unsure which one to read. Here the microcontroller shows the SWR and the dB value as numbers on the LCD, and the reading is taken straight off the display with no scale to interpret.
