2098-007 Frequency Source |
||
| The Model 2098-007 Frequency Source, is a 70 MHz, synthesized frequency generator. The 70.000 MHz signal is generated by the VCO controlled by the Phase Lock Loop circuit which is referenced to a 25 MHz Crystal oscillator. The 70 MHz is applied to an amplifier and then to the output switch/attenuator providing a level of 0.0 dBm (high) or -15 dBm (low). A green LED indicates the presence of DC power. Power is provided by a wall transformer for 115 VAC, 60Hz and provides +15 VDC at 150 ma. The Option -P4 wall power supply covers 90-260 VAC, 47-63 Hz. Specify US, EUR, AUS or UK plug for the -P4 option. The connector is BNC female for the 70 MHz output and the impedance is 75 ohms. | ||
