I recently cheaply got an HP8590b spectrum analyzer (front panel says 50ohm, but option menu says 001, 75ohm) having a dead battery and booting with an error (0030-00000000). After replacing the battery, the instrument does not boot anymore: I have to remove the battery, short the supercap (by a resistor) to <1v and again it boots (with the

We are using E5052B to measure the output phase noise of a DDS module. At 300.01MHz output the measured Phase Noise at 10 KHz offset is -142dBc/Hz. However, when I configure the DDS module for 300MHz Output, phase noise will increase to -130dBc/Hz (12dB Difference). The only difference between these two tones is several near-carrier spurs (less

Потребность в широкополосных услугах связи растет в геометрической прогрессии. Когерентная обработка оптического сигнала и использование современных форматов цифровой модуляции позволяют существенно повысить пропускную способность сетей с 10 Гбит/с и 40 Гбит/с до 100 Гбит/с и еще более высоких значений. Так, например, уже созданы оптические
