I have a pipeline to export a schematic as an ADS netlist, modify the netlist file, then import and simulate the modified file using NetlistInclude. However, it seems that there is an issue with duplicate expressions when exporting a netlist.   An example can be found with the example project in ADS2016_01/examples/MW_Ckts/MMIC_LNA_wrk.7zads. The… (Show more)

I am aware of three ways to export a schematic from ADS in a netlist format: using AEL de_netlist_save() Simulate > Generate Netlist Tools > Netlist Export > Create ADS Front End netlist...   The first two generates the same format, while the last one seems to depend on other options.   To my knowledge, File > Import > Design is the only tool… (Show more)

I'm trying to verify correct operation of a programmable attenuator with LSB attenuation of 0.5 dB. Previous analysis of the SA power uncertainty included SA detector accuracy, power meter uncertainty, and S21 transmission tracking error. In my uncertainty calculation I RSS uncertainty from 2 measurements (no attenuation and tested attenuation).… (Show more)

Hello please where is possible to find or who has got firmware to spectrum analyzer HP 8591A (old version) ? I need U6 U7 U23 U24 and there are 27C512 eprom s. Labeled is 08590-80154 900103  (1990 year).or another version about 1990-91?  In this older type of CPU board is not possible to install 27C010 eproms with newer firmware (PAL array with… (Show more)

Hi!   The integrated waveform generator (license DSOX3WAVEGEN) on my MSO-X 3024A behaves strangely. When generating a "Pulse" waveform and adjusting the frequency or the pulse width, the generated signal wildly jumps around. I would expect that the waveform steadily follows while I'm turning the knob.   Please see the attached scope screenshot.… (Show more)

 My setting got perturbed when I changed from scope mode to TDR. Now when I try to operate in scope mode, I get a random collection of points instead of a continuous waveform. What could be a possible setting change?

I'm having a MSO9404A scope and 1132B differential probe for my testing. I am planning to measure the CAN bus eye mask testing now. Is it possible to do the measure using this. But in my scope the CAN utility measurement is not avialable, Can I use the free trail version in this case? Please confirm urgently.

I have set my scope to 40Ms/s and a time span of 50uS resulting in a expected 2kpts waveform on the screen.  When I then get the waveform with labview I got 32kpts. I don't understand why.  Thanks for any help/tips you can share with me.

I'm trying to help someone use his  8510C, which is tricky, as I don't have one, he lives in Mexico and I live in the UK.   On my 8753ES and 8720D, it is possible to measure S11, put a marker on the Smith Chart, and the Smith Chart display the impedance as a complex number. I'd be a bit surprised if this can't be done on an 8510C too, but he… (Show more)

Good Evening Everyone.  I have just started learning how to communicate with an Agilent 8753ES via GPIB to USB interface, prior to yesterday I did not know what a GPIB interface was, and I have some rather noobish questions that I am hoping for some guidance on.    I have installed Keysight Connection Expert, LabView, and NI Measurements and… (Show more)

Welcome to Tim’s Blackboard! This is the place to find discussions on interesting topics related to signal integrity and power integrity.   This week on Tim’s Blackboard is “Convolution and Single Pulse Response.”   IntroductionTwo weeks ago, in the “Dirac Delta Misnomer” post, I explained why Dirac delta function is technically a distribution. I… (Show more)

I am using the E4980A and AL in an automated test (LabWindows and GPIB). From time to time I get a C reading of 9.90e+43 for DF and ESR I get 9.90e+37. This is impossibly high and I suspect the system is trying to tell me something, but the documentation does not tell me what. Frequency is usually 100kHz, but it moves around.
