Tunable Detector Mount is simple and easy to use instrument for detecting microwave power thro’s suitable detector.

14

Pin modulator

Pin modulator consists of a pin diode mounted inside a section of Wave guide flanged on it’s both end.

15

Ampere meter 0-50 Amp

To measure current flowing through any circuit

16

VSWR meter

The SWR meter or VSWR (voltage standing wave ratio) meter measures the standing wave ratio in a transmission line.

17 CRO The cathode-ray oscilloscope (CRO) is a common laboratory instrument that provided accurate time and amplitude measurements of voltage signals over a wide range of frequencies.

18

20MHZ digital CRO

The cathode-ray oscilloscope (CRO) is a common laboratory instrument that provides accurate time and aplitude measurements of voltage signals over a wide range of frequencies.

19 Cross directional coupler It consists of two rectangular waveguides (called main waveguide and branch waveguide) crossing at a certain angle and sharing a common broad wall.
20 Filter A Filter is a device that passes frequencies within a certain range and rejects attenuates frequencies outside that range.
21 Frequency meter X band It measures frequencies over the X band range with good sensitivity.
22 X band tunable probe for slotted line It is the basic microwave equipment for study of VSWR Attenuation, Phase, Impedance, etc. It consists of a waveguide section in which a small longitudinal cut has been made and a carriage is affixed, which can be moved along the cut by a vernier arrangement. When a tunable detector probe is affixed on the carriage, its tip projects into the waveguide and picks up energy from the guide.
23 Digital Storage Oscilloscope (DSO) For the characterization of microwave devices including diodes and transistors.
24 Phase Shifter A waveguide phase shifter is a two-port component that provides a fixed or variable change in waveguide.
25 S Band Signal Source The S-band falls within the microwave frequency range, typically ranging from 2 to 4 gigahertz (GHz). It is widely used in various satellite applications, including telecommunications, remote sensing, weather monitoring, and scientific research.
26 Liquid Dielectric Cell A liquid dielectric cell measures the dielectric properties of liquids, such as dielectric constant, complex permittivity, and complex effective permittivity
27 Dish Antenna Transmitting and receiving dish antenna
28 Mutli-Hole Directional Couplers Directional couplers are utilized for reflectometer measurements and power monitoring in microwave and RF transmission systems.
29 Magic Tee A magic tee, also known as a hybrid tee or 3 dB coupler, is a microwave component that's used to isolate circuits, mix signals, and divide or combine power.
30 LPKF Board Routers and PCB Board Design Machine This system is used to produce single- or double-sided PCBs, multilayers and rigid or flexible PCBs. In addition, the systems can create high-power circuits, as well as RF and microwave PCBs, allowing extremely exciting product options for electronics.
