掃頻信號源 VHF SWEEP GENERATOR 4410C

廠家: NIHON TSUSHINKI CO.,LTD
尺寸: 41x20x34 cm
重量: 14 kg

An all-solid-state VHF sweep generator, Model 4410C VHF Sweep Generator has been designed and manufactured for testing and adjusting transmitters,TV satellite devices,filters and so forth in VHF band in combination with the oscilloscope.Model 4410c is featured with a number of unique electrical performances, the most noteworthy of which is that the entire band ranging form 5MHz to 500MHz may be swept in one sweep,for Model 4410c to be highly versatile to carry out the measurements and the testings over the broad frequency range, in addition,the osillation frequency being varied by the DC voltage control,the frequency is easy to control remotely,permitting model 4410c to serve as a powerful measuring insturment on the production line capable also of serving as the CW oscillator with output level of 1Vrms(120dB) and containing the attenuator, model 4410c is convenient to conduct the measurement over the broad frequency range.
