THS3001 EVM Specifications 1-5 General Information Note: External factors can significantly affect the overall gain of the EVM. For example, connecting test equipment with 50- Ω input impedance to the EVM output will divide the output signal level by a factor of 2 (assuming the output isolation resistor on the EVM board remains 50 Ω ). Similar [...]

Using The THS3001 EVM 1-6 General Information 1.4 Using The THS3001 EVM The THS3001 EVM operates from power-supply voltages ranging from ± 5 V to ± 15 V . As shipped, the inverting input gain of the module is set to 1, the noninverting input gain is set to 2, and signal inputs on the module are terminated for 50- Ω nominal impedance cables. An [...]

THS3001 EVM Performance 1-7 General Information 1.5 THS3001 EVM Performance Figure 1–5 shows the typical frequency response of the THS3001 EVM using the noninverting input (G = 2). T ypical values show a – 3-dB bandwidth of 340 MHz with a ± 15-V power supply and 260 MHz with a ± 5-V power supply . They also show a – 0.1-dB frequency respons[...]
