How to Order this Product:
Step 1 Use this worksheet to forward the following information to your factory representative:
Model Stability Code Supply Voltage Code RF Output Code Package Code Frequency
C4700 SV120
Example: C4700 C049 SV120 RFH A1 10.000Mhz
Step 2 The factory representative will then respond with a Vectron Model Number in the following configuration:
Model Package Code Dash Dash Number
C4700 [Customer Specified Package Code]
- [Factory Generated 4 digit number]
Typical P/N = C4700A1-0001
Notes:
1
Contact factory for improved stabilities or additional product options. Not all options and codes are available at all frequencies.
2
Unless otherwise stated all values are valid after warm-up time and refer to typical conditions for supply voltage, frequency control
voltage, load, temperature (25°C)
3
Phase noise degrades with increasing output frequency.
4
Subject to technical modification.
5
Contact factory for availability.
