I have been running two kits (one of the older kits with the WiFi mod shown above and the new ARM based kit which uses the same interfacing) with WiFi connected through Lady Heather for over a month without issue. The Antenna Under Test is illuminated by a source antenna at a distance far enough to create a near-planar phase front over the electrical aperture of the AUT. Trimble Thunderbolt Simulator. This applies +5 to the ch 1 select, ch2 select, and /xy select, and a ground to the /chop select. (The MU of the STE9000 procedure is too high for the supplied test data to be of much value for those purposes. 5' x 3. Upload applet Now the Cable Under Test is a 50 feet long cable of 75 ohm characteristic impedance with no termination at the far end (R2 = ∞, or open) and R1 = 0: Voltage at CH2 with 50 feet of 75 ohm cable, R1 = 0 and R2 = open The KO4BB way. . I have been an engineer since before I knew what it meant, always taking things apart to see what made them tick, not always successful putting them back together, but alwayts learning a lot in the process. But if you wish to actually use the supplied test data (that's supplied along with the calibration), then the STE9000 cal is insufficient and you instead want the Standards Lab cal. 602 MHz, which has a power of about 250mW driving a circularly polarized antenna. Once it boots, use the touch screen to change from “Configuration” to “Hard Disk”. fritz-hut. Measuring free running oscillators. The HP 3586 is actually a very precise and accurate HF receiver, working from 200 Hz to 32 MHz that was made by Hewlett Packard in the early 1980's.

Thanks The issue of copyright is serious, but I believe both HP and Tektronix have no problem with the practice of scanning and hosting their manuals of obsolete equipment on publicly accessible web sites they do not control. Put another way, if you just want to depend on your 3458A performing within its published specifications, then the STE9000 cal is probably sufficient. The circuit is extracted from the pulse extender that is part of the ThunderBolt Monitor kit described on this site. A 2. The 7L18, 492 and 494P are quite respectable instruments, even compared to modern gear, in terms of sensitivity, spurs, stability and relatively fool-proof operation. The LTZ1000 is used in HP3458A multimeters and a lot of voltage calibrators from Datron, Fluke, etc. On eBay, “Qservice” is selling the Dallas non volatile SRAM IC DS1225Y, and they even offer optional programming of the SRAM with standard calibration data.

This Tower Construction Pictures. If you do not need the kind of precision and accuracy provided by a GPSDO, the next best thing I can recommend is to find an HP 3586 Selective Voltmeter . The following is a collection of Phase Noise and other measurements made with a Timepod and some auxiliary components. Here is the schematic of the simple CAT interface I use with my FT-817. Please note that the resistor values are not ideal (that's what I had on hand) but when driving a proper 50 ohm load, the attenuation is a very flat 40dB all the way through VHF and still only 1dB off at 500 MHz. You can see the thin film resistors on the right hand side are blown up. How to operate 24V relays from 12V. After we remove the attenuator from the instrument the first step is to obtain the pinout and build us a little test bench consisting of a power meter and a signal generator, the good old 8481D or 8484A will do nicely, if you don't have a signal generator, use the 50MHz calibrator output of the 435 or 436 or similar model. If caugth before the leaking starts, the batterys can be replaced and excanged for 3 regular NI-CD or NI-MH batterys. If you select another directory, make a note of it. copy file, rename it Clock. My Amphenol P/N 57-33500-1 50 pin connector has pins 1,25,26 and 50 labeled on the actual connector. It is interesting to observe that there is a DC offset at the output of the mixer.

Since I host a number of free manuals in pdf on my web site, here my take on the subject: 1) we need quality outfits such as Artek Media, Qservice, AA4DF and a few others. My 8552B had been damaged in transit and the SCAN MODE switch arm lever broken off and missing. Bruce's: Zero Crossing Detectors. The download comes in 2 pieces. Originally designed for use in a linear phase detector there are other applications for which it is suitable. The Prologix adapter provides very significantly faster transfer speed, particularly noticeable on the screen dumps (downloading a color screen dump on a TDS3000 series via RS232 takes several Manuals, Timing, Ham Radio, Test Equipment. Bruce's: Frequency Multipliers And Dividers Multiplying the frequency of a signal by a factor of N using an ideal frequency multiplier increases the phase noise of the multiplied signal by 20log(N) dB. The main considerations are the finish and the insulator. If the oscillator's stability is worse than that of an average crystal oscillator (free running VCO for instance), you can probably simply measure the frequency with the frequency counter and log it to a file. 5 deg as measured from the center to edge of the AUT. wav) Ham Radio Clock. The silver plated types are so much easier to solder that it Precision adapters should always be bought new since its very hard to judge a used adapter, visual inspection and gauging goes a long way but to fully test a adapter you need a VNA with time domain and that's something only a few have.
