** 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.
