** Deviation is referenced to the specified output frequency . For example, inModel CO-233VFW-E at 25°C and 0V control, the frequency is atleast 100 ppm below 10 MHz and at +6V the frequency is at least 100 ppm above 10MHz.
*The following notes apply to options C,F,I,L and N (±200 ppm deviation);
  • They are available at frequencies up to 75 MHz in all models
  • Linearity of ±10% is standard to 75 MHz.
Control
Voltage
0 to +6 V
positive transfer function (lowest frequency at 0 V)
*±3 V to ± 10 V optional
*With bipolar control voltage option, transfer function is negative, linearity is ±10%
Linearity ±20% (±10% optional); ±10% is standard with bipolar control voltage and with deviation/stability options C, F, I, L and N.
Modulation Rate dc to 1 kHz : Higher modulation rates available
Modulation Input Z Greater than 50 K
Aging Rate 3 ppm for the first year, then 2 ppm/year thereafter.
Option "Y" : 2ppm for the first year, then 1 ppm/year thereafter.
Mechanical Tuning Option "T" indicates that a mechanical tuning option is available;
add "T" to model number.
