A closer look at a Marconi Instruments signal generator @ jaeblog: Recently I got a Marconi Instruments 2019 signal generator, capable of generating signals from 80Khz up to 1040Mhz. It can also modulate these signals with AM, FM and more. This instrument is from the mid 80s and is, as far as I can test, […]

DIY AD9833 signal generator
Daumemo has been working on a DIY signal generator based on an AD9833 IC: In this post I am going to continue with the DIY signal generator based on the AD9833 IC where I have left in the previous part. Earlier, I have talked how I had built my first analog signal generator’s stage – […]
SI5351 signal generator test gadget
DuWayne published a new build: I have been spending way too much time playing with the new 3D printer, so have to get back to some electronics. Since the next CWTD.ORG episode is coming up, I decided to build another ‘Test Gadget’. This time it is a Signal Generator based on the SI5351 clock generator. […]
A two channel SI5351 signal generator
DuWayne Schmidlkofer has a nice write-up on building a two channel SI5351 signal generator: After getting the sketches written for the SI5351 board written to support multiple display types, I decided I need to write one more. Now that Pete is moving the Simpleceiver to a single conversion super-het, I will have to worry about […]
Schlumberger 4002 signal generator
Mario wrote an article on reverse engineering a Schlumberger 4002 signal generator: What I got was a Schlumberger 4002 signal generator. It ranges from 0.1 to 2160 MHz with 10-20 Hz tuning accuracy, selectable output amplitude from -138.9 dBm up to +13 dBm in 0.1 dB steps, auto-sweeping and several extras like an OCXO for stability, 20 dB […]
Teardown and repair of an Agilent E4433B ESG-D synthesized signal generator
Teardown and repair of an Agilent E4433B ESG-D synthesized signal generator: In this episode Shahriar repairs an Agilent E4433B ESG-D Synthesized Signal Generator. This 4GHz unit shows the “UNLEVEL” error for all frequencies and at all output power levels. After a close look at the system block diagram the fault is traced to the main […]
HP 8642B backlight Mod
Kerry Wong writes: If you take a look at the picture below, you may recognize immediately that it is a picture of an HP 8642B synthesized signal generator. But if you take a closer look, you probably will notice something different if you have ever used an HP 8642B before. The original HP 8642 series […]
Wavetek 907 signal generator teardown
Kerry Wong did a teardown of a Wavetek 907 signal generator: This Wavetek 907 is absolutely humongous. It has the same width as my HP 5350B but is much deeper (23 in.) and weights around 50 pounds. It was built in 1980 and is clearly showing its age. It was sold as “used” so presumably it […]
USB oscilloscope with signal generator
Jan Henrik wrote this Instructable detailing the build of his DIY USB oscilloscope with signal generator: In this project I want to show you how to make an easy and cheap USB Oscilloscope. Specifications: Price: 20$ Frequency: 2-20000HZ Resolution: 16 Bit Voltage range: +-7V / with probe +-70V Channels: 2 X-Y Mode Signal generator: Sine, Square, Triangular and Sawtooth […]
Turn a smart phone into a signal generator
Jacob Beningo has written an article detailing how to turn a smart phone into a signal generator: Signal generators are a handy thing to have around the lab. They are perfect for testing inputs on a new hardware design and verifying the behavior of a circuit before connecting all the pieces together. In recent years […]
DSO nano signal generator repair
Georg blew out the signal generator on his DSO nano portable oscilloscope. He brought it back to life with a new buffer chip, his repair guide might save your nano too: Spotting the chip on the board is very easy. It’s in an SMD package but fortunately a rather large type. So, although I have […]
