Example 1: When ordering a product with model name: 2570NK, frequency: 20 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: 2570NK – 20.000000M – NSA3285B
Model name – Frequency (up to 9 digits) M – Number for specifying an order
