We are glad to welcome Radio Part as the reference SARK-110 distributor in Japan.
SARK Coax tool is intended to obtain the cable coefficients (K0, K1, and K2) from cable datasheet frequency / attenuation data pairs. In addition, the tool shows a graph of the attenuation or power loss.
The calculated coefficients are compatible with the SARK-110 firmware, SARK Plots, and ZPlots, i.e. in dB/100ft.
The tool is available at the following link: SARK Coax
In addition there is an application note to describe the usage: Obtaining Coaxial Cable Coefficients
We are delighted to announce that SteppIR Antennas has recently been granted an exclusive agreement to offer the SARK-110 Analyzer within North America.
The product is available for pre-order for their first shipment (due January 2015). Online ordering will be made available after the first of the year.
SteppIR Antennas provide an extensive line of high
performance multi-band antennas. Their “frequency-agile” remotely tuned yagi
antennas provide unparalleled mono-band gain and front-to-back performance on
EVERY frequency the antenna covers.
OSL calibration, see User Manual Appendix D, may be performed with pigtail leads having either BNC or SMA series female connectors.
Detector calibration, see User Manual Appendix F, may be performed using the MCX-SMA adapter and SMA loads.
The resistors used in the loads are 0.1% thin-film SMT. The short circuit loads are made with copper foil thoroughly soldered to the plug.
The loads are completely screened but are not waterproof. As the SMT resistors are very small and of a low wattage, the calibration loads should not be subjected to electrical or electronic abuse.
The following items are provided in this set:
a) 1 each – Fixed short, BNC maleFor more information and ordering, please visit http://www.g3tjp.com/
b) 1 each – Open circuit, BNC male
c) 1 each – 49.9 ohm. BNC male
d) 1 each – Fixed short, SMA male
e) 1 each – Open circuit, SMA male
f) 1 each – 49.9 ohm, SMA male
g) 1 each – 100 ohm, SMA male
h) 1 each – 200 ohm, SMA male
i) 1 each – SMA female male to MCX male adapter
