SAF mm-Wave Spectrum Compact 56 – 67GHz Portable Analyzer Review, Teardown & Experiments

In this episode Shahriar reviews the very unique SAF Spectrum Compact V-Band portable spectrum analyzer. These battery powered devices do not require external down-converters, and a particularly useful tool for any field engineer performing microwave equipment installation, link troubleshooting, site planning and maintenance. The analyzers utilize a resistive touch screen, allowing the engineer to wear gloves when using the device. The Spectrum Compact can be used for high precision detection of existing interference on installed paths or available radio channels. Data logging of all spectrum scans is available with the Spectrum Compact device, and enhanced data processing and analysis are provided by SAF Tehnika designed PC software for your laptop.

The instrument teardown reveals a multi-board design and each module’s functionality and design is presented. The unit is then used in several experiments to track and analyze various V-Band RF signals. The review is organized as follows:

01:00 – Overview and model comparison
03:16 – Instrument design, overview power-on benefits
05:23 – Instrument GUI overview
09:56 – Full teardown and analysis of all modules
19:22 – Experiments with various unknown V-Band RF signals
29:43 – PC software overview and capabilities
31:30 – Concluding remarks

Three Interesting Mailbag Reviews & Giveaway! (November 2018)

In this episode Shahriar reviews three mailbag items. There is also a new giveaway! Follow the instruction at the beginning of the video to enter. The reviews are organized at follows:

00:09 – Introduction & Giveaway Details
02:21 – Leo Bodnar Electronic – Fast Pulse Generator

These fast pulse generators are rated to below 25ps! The modules are examined and various microwave and design considerations are explored. The block diagram and functionality of the final output driver is also described in details. The units are used to measure the rise and fall time of various oscilloscopes ranging from 300MHz to 13GHz of analog bandwidth. You can purchase your own fast pulse generator here.

21:11 – SV1AFN GPS Disciplined Oscillator

This GPS disciplined oscillator not only provides frequency synchronization to the GPS clock, it also provides programmable outputs on two independent channels using a Silicon Labs synthesizer IC. The complete module acts as standalone unit which only requires power and GPS antenna connection. The full schematic and block diagram of the synthesizer chipset is presented along with measured output waveform, frequency an phase noise at 1GHz. You can purchase your own GPS DO here.

33:28 – Sain Smart USB-C TS80 Portable Soldering Iron

This soldering iron which supports QC 3.0 is the followup of the very popular TS100 soldering iron. The unit can operate with up to 18W of power from 9V. However, it does not support PD on USB-C. By using the AVHzY USB tester the power bank can be configured to provide any desired output voltage and deliver up to 28W into the TS80 soldering iron. Using this method, the TS80 soldering iron can easily solder large components on a wide ground plane. The TS80 soldering iron can be purchased here or internationally from here. The Ankar PD+ 28600mAh power bank can be purchased from here and the AVHzY USB tester can be purchased here.

Keysight Keysight UXR 110GHz BW, 256GS/s, 10-bit, 4-Channel Real-Time Oscilloscope Teardown & Experiments

In this episode Shahriar takes a look at one of the most advanced electrical test and measurement instruments ever created. The Keysight UXR-Series Real-Time Oscilloscope brings 110GHz of analog bandwidth and 256GS/s real-time sampling at 4-channels simultaneously. To make it even more impressive, the entire data-conversion architecture is in 10-bits. This implies that the instruments captures, processes, stores and displays over 10Tb/s of information.

Various architectures of state-of-the art oscilloscopes from Keysight, LeCroy and Tektronix are examined and compared against the new real-time architecture of the UXR-Series oscilloscope. The teardown of the front-end 110GHz module along with the data acquisition board is presented and analyzed in detail. The instrument showcases a wide range of Keysight technologies implemented in various technologies such as InP, SiGe BiCMOS, 65nm CMOS and 28nm CMOS nodes. In combination with Hyper-Cube memory module, data can be captured at 256GS/S from all 4-channels at the same time. Several variants of the UXR-Series oscilloscope will be available from 13GHz to 110GHz bandwidths.

A new calibration probe is also introduced based on the Keysight InP process capable of producing signal edges with sub-3.5ps of rise/fall times with NIST traceable calibration data. This enables users to perform NIST alignment and bandwidth calibration on site without needing to send the instrument back to Keysight.

Several measurements with the scope demonstrates its extraordinarily low noise floor, jitter as well as the capability of the new probe module for instrument calibration. The 110GHz 4-channel variant of the UXR-Series oscilloscope has an MSRP of $1.3 Million US dollars.
