n How to Specify an Order
Example 1: When ordering a product with model name: 2765E, frequency: 40 MHz,
frequency stability: ±100 x 10–6, and power supply voltage: 3.3 V
When ordering our products, specify them with an “Ordering Code” that consists of the following:
Ordering Code: 2765E – 40.000000M – NSA3393A
–
–
M
Number for specifying an order
Model name Frequency (up to 9 digits)
