Example 1: When ordering a product with model name: 2560NK, frequency: 80 MHz,
frequency stability: ±100 x 10
–6
, 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
Model name – Frequency (up to 9 digits) M – Number for specifying an order
