HAM Radio Meter & Test Equipment

DX Engineering RF Attenuators

DX Engineering RF Attenuators are used inline with receiving equipment for testing purposes. An inline attenuator will limit the RF input to preamplifier to prevent overload or be used to pad the output of a high gain preamp to an appropriate level. Adding an inline attenuator to a receiver input allows determination of accuracy of s-meter readings on transceivers with a constant RF input signal source. Sometimes, the level of low power RF equipment needs to be reduced for measurement or to obtain the proper input level to an amplification device, such as with QRP equipment. Specifications of impedance, attenuation, power handling and connectors appear on the part number description. Order inline RF Attenuators for your test bench or shack from DX Engineering.

DX Engineering OSL Calibration Sets

DX Engineering OSL Calibration Sets provide the high quality standards required to take advantage of the Open-Short-Load Calibration capability on specific RigExpert Analyzer models, AA-55ZOOM and higher. The advantage of this ability is to adjust for the coax cable being used, so the analyzer will display the "true" characteristics of the antenna under test, as if the analyzer were connected directly to the antenna feedpoint. The inherent analyzer calibration has its "reference plane" set to the analyzer connector. However, the advanced RigExpert analyzer models allow "recalibration" to be toggled on, to use these Open-Short-Load calibration standards to reset the reference plane. Calibrating with these standards at the far end of any 50-ohm coaxial cable assembly subtracts the electrical parameters of that coaxial cable and its specific length, a process referred to as "nulling" the cable. This allows the analyzer's measurement reference plane to be moved to the far end of that transmission line for accurate measurement of any antenna in its proper operating location. DX Engineering OSL Calibration Set standards are built into high quality silver-plated chassis mount SO-239 (UHF female) connectors. They are self-explanatory in their appearance. The Open standard has no connection from center to shield, the Short standard has a short circuit tab soldered from center to shield and the Load standard has a shroud over a potted, extremely accurate, 50-ohm load resistor. They include a beaded tie to keep them together in your analyzer tool kit. The procedure for using the Open-Short-Load standards is described in the applicable RigExpert manual Annex titled Calibration. To reset the reference plane of the analyzer to the end of a coaxial cable, in order to accurately measure an antenna, perform an Open-Short-Load calibration on the specific coaxial cable assembly to be used. 1. Select Calibrate in the Main Menu (or press F+2 keys) 2. Follow the on-screen three step instructions, sequentially connecting the Open, Short and Load standards to the opposite end of the coaxial cable to be used. 3. To apply calibration to any sweep, toggle on or off that specific cable null calibration by pressing F+2 and the "CAL" icon will appear at the bottom corner of the analyzer screen.

You also have your choice of reading power in Watts or dBm. With Coaxial Dynamics LCD Display Directional RF Wattmeters you may now measure RF Power in 50-ohm coaxial cable and transmission lines. Required Coaxial Dynamics standard Plug-In Elements, purchased separately, are readily available for frequency ranges in HF, VHF and UHF, in typical power ranges. Select frequency and power range specific elements are available by special order to allow measurements as low as 0.45 MHz and as high as 2.3 GHz, in power ranges from 100 mW to 10 kW! Because of the LCD's low power consumption, the internal rechargeable batteries can be used for many hours before recharging (batteries and AC charger included), so they're well suited for field or portable use. A heavy gauge, all-metal case protects the wattmeter from impact shock and a real leather strap makes transportation safe and comfortable. For added convenience, two sockets for storage of additional plug-in elements are located on the back of the unit. Note: For additional product information, please look at the files under the "Documentation" tab. Coaxial Dynamics LCD Directional RF Wattmeters offer commercial quality, accuracy and flexibility that Amateur Radio operators can actually afford! Order one of your own Coaxial Dynamics LCD wattmeters from DX Engineering and monitor your power from across the shack!

Palstar PM2000A Watt Meters

Palstar PM2000A Watt Meters measure and display SWR, forward power up to 2,000 watts, and reflected power simultaneously on a dual movement meter system that operates in the frequency range from 1.8 MHz to 60 MHz. Accuracy of the readings is assured with the PM2000A shielded directional coupler. These backlit meters, which can display average or peak power readings, now have a convenient peak hold function and a push-button selection for 300 watt and 2,000 watt ranges. PM2000A Watt Meters are the improved version of Palstar's best-selling WM150 Wattmeters. When QST tested the PM2000As' predecessor, they found it to be the only wattmeter with true Active Peak Reading. The PM2000As are one of the new generations of watt meters from Palstar. All of the features of the WM150 are integrated into PM2000A meters, now with increased power capability up to 2kW and two-second peak hold metering. To top it off, just like on Palstar tuners, the PM2000A meters have an 11 ga. (0.090 in.) iridite-treated aluminum case with a powdercoated front panel and top cover. Rear panel SO-239 (UHF female) connectors are provided for coaxial cable RF input and output, and a 2.1mm connector provides input for 12 Vdc at less than 200 mA to run the meter circuit and backlight. Note: For additional product information, please look at the files under the "Documentation" tab. Simple to hook up and use, Palstar PM2000A Watt Meters take the guesswork out of your inline RF power and SWR measurements. Order yours from DX Engineering today!
