500KHz-2.5GHz RF reflection bridge standing wave ratio measurement VSWR 40dB

Description

500KHz-2.5GHz RF reflection bridge standing wave ratio measurement VSWR 40dB
The RF reflection bridge is mainly used for measuring the reflection characteristics of various RF devices (especially the antennas). It is a tool that is both economical and very good. The reflection bridge is the core of all RF vector network analyzers. . If you only have a spectrum analyzer (preferably with a tracking source) or a radio integrated tester or sweeper, as long as you match this baby, you have the most common function of the network analyzer (test standing wave ratio or see) Callback loss)! !
Suitable for a variety of radio enthusiasts, companies, universities and research institutes to measure passive device standing wave ratio, especially measuring antennas, debugging small signal amplifiers, filters, and so on. Can be well matched with RIGOL DSA815 spectrum analyzer, HP8590E, HP8591E, HP8560E, R3361A and other spectrum analysis and comprehensive measurement with tracking source! Because the output power of the instrument tracking source is generally adjustable, these instruments can be used to debug the input matching of various small-signal RF amplifiers after adding the bridge. It can truly measure the input matching of the circuit design under the small signal input state. Happening.
If you don't have a tracking source in your hand, you can use another independent RF signal source to achieve VSWR. It is a bit of a hassle. You can only test one frequency point and multiple tests every time you adjust the signal source and spectrum analyzer. After a few points, you can make a curve, you can still replace the sweep tracking source, haha!
This baby is especially suitable for debugging short-wave antennas, FM radio antennas, UV walkie-talkie antennas, 315MHZ, 433MHZ remote control antennas, mobile communication 800MHZ 900MHZ antennas, WIFI, Bluetooth 2.4GHZ antennas.
Baby indicator:
Operating frequency: 500KHZ to 2500MHZ (excessive operating frequency range)
Orientation: 40DB typical value (500KHZ to 30MHZ directionality 30dB,
Directivity 40dB from 30MHZ to 2000MHZ,
2000MHZ to 2500MHZ directionality 27dB)
Insertion loss: 13dB (RF input to reflection test port)
Port standing wave ratio: less than 1.3
Maximum input RF power: 20dBm
RF interface: All three ports are SMA female (external thread inner hole, gold small threaded head)
Although the outer casing is a plastic case, the inside has a good magnetic material shielding, even if the plastic case can well complete the shielding function, the bridge has no shielding performance defects, and the product itself is light and compact.
Product wiring and usage
The wiring diagram is as follows. The left interface of the figure is connected to the spectrum analyzer tracking source when the RF signal input port is used.
The intermediate interface is the interface of the device under test. When connected, it is connected to the device under test.
The rightmost interface in the figure reflects the output port and is connected to the signal input port of the spectrum analyzer.
