How to Specify an Order
n
Example 1: When ordering a product with model name: 2560NK, frequency: 80 MHz,
–6
frequency stability: 100 x 10 , and power supply voltage: 5.0 V
When ordering our products, specify them with an “Ordering Code” that consists of the following:
Ordering Code: 2560NK – 80.000000M – NSA3285A
