How to measure voltage with a tester - choose the voltage (unit "V") parameter, then insert the test leads (black and red). Connect to a circuit and read the value.
During network deployment, a loopback usually occurs on a Tx-Rx interface because optical fibers are connected incorrectly or the interface is damaged by high voltage. In Figure 7-5, a self-loop occurs on an interface of the switch. As a result, packets sent from this interface are looped...
How high voltage should be set for VREF and VCCD on CY8C4248LQI-BL583? on spec, they are 1.024V and 1.8V, respectively, but measured values are ~0.0 for both. Solved! Go to Solution. Like Subscribe 571 0 3 View all forum discussions Previous Topic Next ...
This article shows how to use a high-voltage, high-current-drive op amp in a 4–20mA current-loop application. The op amp converts a voltage signal from a DAC into a ±20mA or 4–20mA current output. Application experiments feature the MAX9943 op amp. Test data are presented. Basics o...
High power draw brings a couple of disadvantages: it reduces the CPU’s lifespan, increases heat output, and leads to higher electricity bills. To get thattemperature sweet spot, users can undervolt their CPUs. This can be achieved by reducing voltage requirements while keeping the CPU speeds ...
You can also run the display transceiver diagnosis command to check optical parameters of the optical interface. <HUAWEI>display transceiver diagnosis interface GigabitEthernet 0/0/8 Port GigabitEthernet0/0/8 transceiver diagnostic information: Parameter Current Low Alarm Hi...
Ir1_2is the current through the resistive divider to GND. Ifbis the feedback bias current from the datasheet. This ensures less than 1% inaccuracy in the voltage measurement. However, lower resistor values can increase power loss in the resistive divider, which may be unsuitable for high-effi...
How can you easily select the right coil for high voltage inverting buck-boost topologies? Answer: By using simplified duty cycle equations to plot the coil current ripple vs. the input voltage for the output voltage of our circuit, then validating the findings with LTspice®. Introduction ...
Reducing GPU power consumption can be achieved by underclocking, which decreases clock speeds. Undervolting, on the other hand, lowers the incoming voltage without affecting the card’s fundamental and memory clock. You can use both, but we have to warn you that undervolting is much more lik...
is measured by leakage current. Knowing the leakage current and applied voltage, the insulation resistance can be calculated based on the ohm’s law. There are two basic ways to measure the leakage current. First, apply an ammeter in series with the capacitor and voltage source (see Figure 1...
