Refer to Table 8 for Standard Frequencies. Other Frequencies are available on request. Check with factory. 2. Output DC-cut capacitor is optional. 3. The VT-704 power supply pin (Pin4) should be ltered using a by-pass capacitor of 0.1uF for optimal performance. 4. Referenced to the midpoint between minimum and maximum frequency value over Operating Temperature Range. 5. Frequency measured at 25 C, 1 hour after 2 IR re ows. 6. Referenced to Mid Control Voltage 7. Measured at ambient temperature using Agilent E5052B Signal Source Analyzer. Page2
