The unit will not generate Frequencies above the limit Frequency selected in this menu item.
The limit Frequency will be stored in non-volatile memory until changed in this menu item.
1.4.8.2 Power Unit
In the
SETUP->OUTPUT->POWER UNIT
menu the user may select either a relative power output
ranging from 0% to 100% of the units’ power output capability, or an absolute output power selected
in dBm (between -40dBm to +10dBm).
Setting relative mode is useful if the maximum power output at any given frequency is desired from
the analog RF Output BNC connector on the front panel. The maximum output power in relative
mode can range from +5dBm to over +18dBm depending on the output frequency.
Setting absolute mode will allow the unit to generate RF signals with high level-accuracy (typically
-0.2dBm at an output power of 0dBm). The range of the output power is limited to -40dBm
to +10dBm in absolute mode.
This setting only affects the analog RF Output BNC connector on the front panel. All other signal
outputs remain unaffected by this setting.
1.4.8.3 Power Limit
In the
SETUP->OUTPUT->POWER LIMIT
menu the user may limit the maximum possible analog
RF Output Power that can be set via the front panel keys in the frequency setting menu. This setting
will also affect sweep modes, and memory recall modes.
The unit will not generate Power levels above the limit Frequency selected in this menu item on the
analog RF Output BNC front panel connector.
The limit Power will be stored in non-volatile memory until changed in this menu item.
This setting only affects the analog RF Output BNC connector on the front panel. All other signal
outputs remain unaffected by this setting.
1.4.9 Setting up Frequency Sweeps
The unit can be used as a sweeping signal generator. The following parameters are selectable through
the keypad menu:
•
frequency start (F1, from 0 to 1.64 Ghz)
•
frequency stop (F2, from 0 to 1.64 Ghz). The stop frequency has to be different to the start
frequency and may be selected to be lower than the start frequency.
•
duration (D) of the sweep from 0.1s to 1000s with a resolution of 0.1s.
•
sweep spacing (pace): linear or logarithmic
•
sweep mode:
– from F1 to F2, single sweep only
– from F1 to F2 and back from F2 to F1, single sweep only. In this case the total duration of the
sweep time is doubled.
– from F1 to F2 continuously sweeping until the Right key is pressed. Every sweep from F1 to
F2 will have a duration D, and the unit will restart at F1 once F2 has been reached.
