I am trying to get the value of the h field with a horn antenna as a reference antenna. I used a 90 degrees waveguide twist with the horn antenna in preset to measure le level of the received signal. But I am getting strange values. Am I proceeding the right way to measure the h field? If yes is it a scaling issue if the values that I?ve got? I
Hi, For the error "incorrect ports" in Calibre LVS hierarchical run, why do some ports appear at the top level and others at the IP level ? What is the basis for them to appear at two levels like this ? Thanks, Aditya
Hello, I'm new to the forum but hopefully you guys will give me some great advice. I have been programming microcontrollers for the past five years, only as a hobby but I do plan to move to this as my career, I am currently a machinist but I don't quite have the means for university yet. I'm 27, so should still be capable of learning :razz:
Hi everyone, I am going to use SMD fuses for protection needs of the electronics. Which way is better, using current rating of: 6A 0603 package SMD fuse or three 2A 0603 package SMD fuses? Using three fuses in parallel instead of one makes more sense to me since; Each one of them will get hot lesser, Since smaller current capacity (...)
I can imagine three different ways to connect the anode (OUT, GND, Supply+), please ask a clear question.
Those two new blue upright capacitors are probably unsuitable. I can see you folded the wire to make radial construction fit an axial footprint and the values might be correct but check they are rated for 105C temperature and are low ESR types. The wrong types will work fine for a while but nowhere near as long as the correct ones. Very often on
Can the momentum simulation results be better than the simulation result of the schematic?
How can I measure the average points of the peak if these signals and one avg of max&min value of sine wave. Note that I'm new with dsPIC ics but have been working with PIC and atmel ICs for a long time. Yes, I can do it in my older method but those are time consuming for this product. That is why I'm asking for suggestion from experienced friends
Hi I want to combine 8 loop antennas into one structure, each of them at a different angle to the others. By using 8 relays, I want to select each of these 8 loops so that I can null a signal at a wanted direction. So instead of using a single loop and a rotor, to use multiple loops and select each of them. Now the problem I have is that I have on
This has nothing to do with LEDS :) Many power converters are liable to saturate the transformer under unbalanced conditions, I am looking at a full bridge with a bridge rectifier output so there are plenty of oppertunities! The standard method to reduce the problem is to use peak current control. In my case I wish to use average current mode, a
I repair Satellite receivers and I often need to block the DC voltage on the IF line to do the repair . I need to block 13-18 Volts between 900mhz and 2Ghz while obviously letting the AC signal pass. If anyone can suggest a simple circuit I would greatly appreciate it.
I have a cooktop which SMPS is bad. It should produce 24VDC but it only does 16V. Here is a schematic with a very similar topology. It works with a TOP254GN IC. For first I tried to change 3 main components as all other parts looks fine and as these 3 tend to fail on this panel as I read on forums: - D6 Diode (original SMD mark: T4X5) -> r
Hello all, I hope someone can help. I have short violations in my low power design. They are happening inside my power domain (i have an internal power net that is routed by Special Route in the power domain), and it happens with Tap Cells, Encap cells and Fillers only. Power swicthes and regs are not having shorts. I don't understand why thi
Hi everyone, I've encountered the same trouble than maxim10373 while looking for a replacement for the ON5134. After some research, I've found that BU508AW is a correct replacement for this transistor. The supply is now repaired using this reference. To go a bit more deeply in the reparation, I have changed all the aluminium capacitors. One
That example only works if the bits are in the same port. The 'MY_REG' in post #1 used bits across three different ports. Brian.
Hi, I have a circuit which reads 24V, scales down to controller compatible voltage and controller reads HIGH when 24V is connected, else 0 when 0V is connected. Essentially its a positive logic. 24V = HIGH and 0V = LOW. If I want to convert the same circuit to a NEGATIVE LOGIC i.e 24V = LOW and 0V = HIGH, what would be simplest way without chan
I've been working on a transceiver system with BGT24LTR11 chips at it's core and I was unable to achieve necessary signal to noise ratio. I want to know whether it's theoretically possible and for that I need to understand how the terms in the title all intertwined. The following parameters/figure of merit I'm familiar with: Minimum detectable
Hello! I'm trying to smoothly brake a three phase brushless DC motor by short circuiting the phases. At this moment an overvoltage occurs damaging the power circuit. Is this the right way to do it? Thanks
Hi I am using ADS62p49 14 bit adc which supports LVCMOS and LVDS output. I have a low sampling requirement of 30MSPS hence I am using LVCMOS type output in 2's complement form. When I give 10dB sine wave input to the adc, I get a sine wave digital output with dc bias. Similarly when I am giving no input, I should get lower bits triggered rest all
Hi I am using FMC150 Daughter card which has 14 bit TI ADC which can be configured for both LVDS and LVCMOS type output to carrier card. When I am setting the adc in LVCMOS mode with 2's complement digital output, I am having the output bits raised by 2^13. So my output is always in unsigned mode with DC bias of 2^13. If I am giving no input signal
