Hi all, I need a HF (1MHz - 50MHz) AM/SSB Modulation monitor to adjust and monitor the amount of modulation of my CB rig using a small analog meter (50uA needle meter). This will be part of my SWR / power / Modulation meter. 73, Fernando - Call sign PU2PLL - Brazil
Hi, I would like to estimate the power consumption of my ASIC design at each clock cycle. At the moment I have set up the following flow: 1) Generate the netlist using RTL compiler. 2) Dump the VCD file using NC-sim and the netlist obtained at step 1. 3) Back in RTL compiler, for each clock period I want to monitor I annota
I think what it is doing is measuring voltage directly across the battery and using a Hall sensor to monitor the current to one or more batteries in a chain (the current will be the same in them all as they are in series). That allows power to charge the battery to be measured and power drawn from the battery to be measured but I can't see (...)
See if there is an advanced menu by turning on the display with holding power and SELECT buttons down for at least one second. Larry G
That sounds very much like video signal creeping into the audio stages, especially as it changes in time with the picture content. 15KHz is probably the picture scan frequency so it points to either a loose grounding point or a capacitor on the power feed to the monitor section being faulty. Brian.
Field probes with l<<λ are often used in EMC laboratories to monitor field strength in susceptibility tests. Their output can be interpreted as power density under certain prerequisites (e.g. far field or quasi far field conditions). The field probes are terminated with high (ideally infinite) impedance, in other words there's no received p
Hi Gib, The power flow should be the integral of the Poynting vector through the specified plane. To do this in CST MWS, you should first define an analytical face (the face is just for analysis, and does not interfere with the model) at the plane you are interested in. The power flow monitor should be activated prior to running the (...)
We are trying to calculate the Feedback loop Bode plots for a 48Vin to 48Vout,3A converter using a PRM48? SMPS module (as on page 18 of the PRM48? datasheet below) As such we wish to calculate the gain & phase margin of this we can check it will be stable. The details of the power stage inside the PRM48? module are not given in th
Like any arc, the power conducted occurs at low voltage after the high voltage trigger. Simply use a low pass filter and the fast transient RF will be filtered. Start with 100Hz LPF to monitor both V and I then multiply. When I monitored 100kA diffusion welding below 6V back in the late 70's , I used shielded twisted pair at right (...)
If your high side voltage is above 2v then the ZXCT1009 chip will work fine. Unless your high side voltage falls below 2v and you still wish to monitor the current, than you will probability have another source to power the shunt amplifier available. Any op amp that has a common mode voltage reaching down to zero would be more appropriate.
A VNA measures network parameters, including the power gain between ports, but isn't the appropriate instrument for measuring absolute power. A spectrum analayzer/signal analyzer is the proper instrument for that. Using a VNA to measure the S parameters of a transmitter/receiver could allow you to calculate the received power, if you know (...)
it is used in Dell monitor power supply board and i cant find it in market please give datasheet and substitute information for it.129777
Hello to all, I need some help fixing the power supply of the mentioned monitor. I turn on the monitor, it is working fine for a second or two, and then the backlight goes off. The problem is with the inverting part of the suply that powers the backlight of the monitor (650 volts AC). I have come to (...)
Dear All, I have a 3V coin cell battery to power RTC logic in my controller. I have calculated the lifetime of the battery and its coming around 3+ years. But I want to design a circuit which tells when battery voltage will go down to certain voltage (say 2.4V) and give a signal to controller. I have very less space in my board, so a simpl
i need to monitor current , voltage, power factor, active power, real power. kindly suggest any low cost ic that can measure all the above for 3 phase thank you
go to simulation -- field monitor -- and select power flow and other parameters there. once simulation completed, you can view 3d results or power at specific angel/direction as you requested.
I need to design a low cost power analyzer for my thesis work (solar inverter system) as one is not available and their is no plan to buy a new one. power Analyzer will only be used as an instrument for measuring electrical signal of characteristics 230VAC; 0.5-10 Amps. current; Single Phase and frequency 50Hz. I have access to Infineon Relax Kit
Hi, I wanna add battery for internal rtc and when power get off, device will run until battery charge off. So I have to add chargable lion battery in schematic. Anyone can help to adding battery and charging part. I use pic18f66j65 microcontroller. Thanks you
Hi, what are "these phone type batteries"? Do you have technical data? i want to use these phone type batteries and get 3.3v 300mA , any recommendations for battery that has higher voltage than 3.3v since i will be using a LDO to get 3.3v regulated output. Using 9V batteries to generate 3.3V / 300mA with a LDO.... is wasting about
Doesn't explain USB interface damage, but USB specification require a self-powered device to monitor the VBUS line and not to drive to bus lines before a voltage has been detected.
