input connector of another device, the device can be phase-locked to the internal reference
signal of the E5070B/E5071B and used under this condition.
Connector type: BNC connector, female

12. Serial Number Plate
The seal showing the serial number of the product.
13. Certificate of Authenticity Label
The label showing the information of the “Certificate of Authenticity.”
14. Rear USB port
A USB (Universal Serial Bus) port (number of ports: 2) specifically installed for an ECal
(Electronic Calibration), a USB/GPIB interface, a multiport test set or a printer. The
specifications of this port are identical to the “12. Front USB Port” on page 39.
15. Reserved Port (Reserved)
These two ports are not available for connections.
16. Printer Parallel Port
A 25-pin parallel port for printer connection. Connecting a designated printer to this port
allows screen information on the E5070B/E5071B to be printed. For more on printing, see
“Printing Displayed Screen” on page 369.
17. Mini-DIN Keyboard Port
A port to which a mini-DIN type keyboard is connected. The keyboard can be used to edit
VBA programs inside the E5070B/E5071B or to enter file names. Since the arrow keys and
numeric keys on the keyboard work in the same way as the arrow keys and numeric keys
on the front panel of the E5070B/E5071B, you can use it instead of front panel operation.
NOTE
Be sure to only use a keyboard designated for use with this instrument. Using a keyboard
other than those designated may cause erroneous input.
