Enabling a Software Option
1. A license key is required to enable each software option. This license key is provided on 
the license key certificate that you receive when you purchase the software option. 
Access the Software Options menu by pressing 
Utility > Instrument Adjustments > Software 
Options. An example of the signal generator display follows:
Verify that the host ID shown on the display matches the host ID on the license key 
certificate. The host ID is a unique number for every instrument. If the host ID on the 
license key certificate does not match your instrument, the license key cannot enable 
the software option.
2. On the display is a list of software options that are already enabled (if any) and the 
software options that can be enabled. Software options are linked to specific hardware 
options. Before a software option can be enabled, the appropriate hardware option must 
be installed. For example, Option UN5, Multi-Channel CDMA, requires that 
Option UND, Internal Dual Arbitrary Waveform Generator, be installed. If the software 
option that you intend to install is listed in a grey font, the required hardware may not 
be installed. (Look for an X in the “Selected” column of the appropriate hardware option 
in the Hardware Options menu.)
3. To enable the software option, highlight the desired option using the up/down arrow 
keys or the front panel knob.
4. Press 
Modify License Key. Enter the 12-character license key (from your license key 
certificate) using the softkeys and numeric keypad. When you have finished, press the 
Enter terminator softkey.
5. Press 
Proceed With Reconfiguration > Confirm Change to verify that you do want to 
reconfigure the signal generator with the options for which you have provided a license 
key. The instrument will enable the options and reboot.
