I just purchased a few more pieces of test equipment and now I don't have space for any projects…So, I am offering the following for sale. I would rather sell this gear to Amateurs and the asking prices are less than what you would see on Ebay or elsewhere. Everything is in very good shape and top quality, passes all self-tests, etc.
Hewlett Packard E4432A ESG-D3000A Digital RF Signal Generator. 250Khz-3Ghz. This is an excellent, modern signal generator that is very easy to use and has excellent level accuracy. It has a wide range of internal modulation modes and the modulation generator can be output as a function generator. In addition to the analog RF functions, the generator has a broad range of digital features. This particular signal generator has the 1E5, high stability time base and option UN3. The data sheet is downloadable from https://dl.dropboxusercontent.com/u/8297661/HP_ESG_DSERIES.pdf. The generator doesn't have the HP/Agilent feet, but they are readily available on eBay for $10 to $20 if you want them. (Agilent is the successor to HP's test equipment division and this generator was sold as an Agilent, too. Downloadable manuals are on the Agilgen site.) There are photographs of the generator feeding a 500Mhz, -30dbm signal into an HP 8594E spectrum analyzer. https://dl.dropboxusercontent.com/u/8297661/IMG_0418.JPG%20%282%29.JPG https://dl.dropboxusercontent.com/u/8297661/IMG_0417.JPG%20%282%29.JPG https://dl.dropboxusercontent.com/u/8297661/IMG_0416.JPG Price $1,600 plus shipping and insurance. Rohde & Schwartz CMTA-84 Communication Analyzer with URV. It is very hard to sum up the CMTA-84 because it does virtually everything, 1Ghz signal generator controlled by a high precision OXCO. There are two audio oscillators to provide audio out and modulation (both can be operated simultaneously). Frequency counter, power meter, 15Mhz oscilloscope, audio spectrum analyzer, RF spectrum monitor, RF voltage measurement, AF voltage measurement, DC voltage and current, automated measurements for S/N ratio, distortion, SINAD, programmable and more. You can connect a transceiver to the unit and run a full set of diagnostics manually or from a saved program. I also have the very hard to find URV-Z7 probeset for the RF voltmeter with 20db and 40db attenuators in its original case. It took me several years to find this and the only other that I have seen was being sold for 350 Euros. The CMTA84 has the front and back protective covers, the basic manual and I have a photocopied manual from a CMTA-54 (similar except for the spectrum analyzer/rf monitor). If you don't have a workbench that will support lots to tools, this is a super choice. R&S RF gear is among the best in the world. I have put a CMTA84 brochure at https://dl.dropboxusercontent.com/u/8297661/datasheet_CMT.pdf and photograph of the front panel with the RF Spectrum monitor in operation. Price, $1,750 plus shipping and insurance costs. Tektronix DSA602A and 11302A oscilloscopes, plus probes and plug-ins. If you do have space on your workbench, these are marvelous instruments in the Tektronix 11000 series. The DSA602A is a color oscilloscope with a base bandwidth of 1Ghz (depending upon plug-in) with 4 500 MSa/sec digitizers that can be interleaved automatically to produce 2GSa/sec on a single channel. This is plenty for most uses. It has a gorgeous Sony Trinitron color crt and uses an innovative infrared touch screen plus conventional controls. Because it is digital, it is capable of a wide range of automatic measurements, calculations and analyses. It can, for instance, look at the signal in the frequency domain using Fast Fourier Transformations. The DSA602A has the Option 4C extended memory. It is a very precise scope and shares plug-ins and probes with the 11302A. The 11302A is an analog scope using a microchannel CRT. This is similar technology to light gathering night glasses and is used to provide a bright trace for ephemeral events. So, if you are chasing a glitch that won't show up on a digitizing scope (you have to assume a really fast event), then the 11302A is the right tool. It also has a built in frequency counter. I have the following plug-ins that work with these and probes for these scopes. Plug-ins (3) 11A32 2 Channel, 400 Mhz 50 ohm/1meg ohm (1) 11A34 4 Channel, 300 Mhz 50 ohm/1 meg ohm (1) 11A33 Differential Comparator (1) 11A52 2 Channel, 650 Mhz 50 ohm (1) 11A72 2 Channel, 1GHz 50 ohm Probes (2) P6134c 400 Mhz, 1 meg ohm. Purchased by me new, still have original vinyl pouches. Very little use. These are the standard probes for the DSA602A and 11302A. (1) P6135a Differential pair. The P6135a is a matched pair, but is missing the plastic screw on sleeve that goes over the tip on one of the probes. I have a number of spare sleeves, but mine are not the correct size. (1) P6156 3.5 Ghz 50 ohm probe, unused and in orginal Tek hard plastic case. I also have the original manuals for the DSA602A and I have upgraded this unit to the last firmware revision. Is there a downside to these scopes? These were meant to be used in labs and they are big and heavy. So, you will need bench or cart space and you won't be taking them on field day. But if you have the space, they are superb. It would be best if these were picked up in person, rather than shipped because of the size and weight. Price for entire 11000 system, DSA602a/11302A, plus mentioned plug ins and probes is $1,300. This is an amazing amount of capability for this price. Please don't ask to break up the system. This should be picked up in Alameda, CA because of size and weight. Tektronix TDS784D Digital Phosphor Oscilloscope. This is a later generation 4 channel scope with a bandwidth of 1Ghz and a sampling rate of 4GSa/sec on one channel or 1GSa/sec on 4 channels simultaneously. It has even more power than the DSA602A, and is smaller and lighter. It uses a lcd shutter over a CRT to provide a color display. I have just replaced the CRT/Shutter (very hard to find) and it has less than 1 hour of use since replacement. This is very important because some DPO scopes have dim screens. Also, the scope was calibrated in January of this year, so it is still in calibration. A DPO scope can simulate an analog scope because it provides information concerning the repeatability of an event through gray scale/color presentation. It, thus has some of the best attributes of a digital scope (digital precision, analysis, storage) with the analog scope's real time display of events. The TDS784D also has a VGA output that allows you to send the display information to a computer monitor or projector. If the scope is picked up in Alameda (saving me the effort of packing), I will throw in a Dell flat screen monitor that can be used with the scope. Photographs showing the front panel and displaying a 100 Mhz signal are at https://dl.dropboxusercontent.com/u/8297661/IMG_0622.JPG and https://dl.dropboxusercontent.com/u/8297661/IMG_0621.JPG. Price $1,950 plus shipping and insurance. -- Howard Ashcraft W1WF ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
