1.  AC Power Cord Connector 
The AC power supply specification of RSA3000E is: 100-240 V; 45-440 Hz. 
2.  Fuse Holder 
You can replace the fuse. The fuse rating supported by the instrument is AC 250 
V, T3.15 A. 
3.  OCXO (Option) 
OCXO (Oven Controlled Crystal Oscillator) can provide a highly stable frequency 
reference over temperature variations. For order information of the option, refer 
to the datasheet manual. Note: A 40-minute warm-up is required for OCXO to 
reach its nominal frequency. 
4.  Handle 
You can rotate the handle upright and make the portable instrument easy to 
carry. 
5.  10MHz IN 
RSA3000E can use the internal or external reference source. 
  When a 10 MHz external clock signal is received at the [10 MHz IN] 
connector, this signal is used as the external reference source. At this time, 
the status bar of the user interface displays "Ext". When the external
