4 Instrument Functions
This chapter explains the functions of the signal generator and the options available in the setting
menus. The associated IEC/IEEE-bus command is specified for each parameter (where applicable).
The description begins with the general instrument settings which do not directly affect signal
generation. The majority of these settings can be accessed by means of front-panel key menus and not
by means of function block menus.
The signal generation functions are then described, beginning with the functions which affect the RF
signal (RF block) and the analog modulations (Mod block). The configuration of the modulation
generators (LF generators and pulse generator) and of the LF sweep is offered in the Mod Gen
block.The general instrument settings include various functions, such as:
• Setting a defined basic setup using the
PRESET key
(section "Default Instrument Settings - Preset Key", page 4.2)
• Switching from remote control to manual control using the
LOCAL key
(section "Switching to Manual Control - Local Key", page 4.17 )
• Configuring the generator and its interfaces in the Setup menu - e.g. setting the IEC/IEEE-bus
address, starting an adjustment, querying instrument data
(section "General Configuration of Instrument - Setup Key", page 4.3)
• Calling up the online help using the
HELP key
(section "Help - Setup-Help", page 4.17)
• Querying messages using the
INFO key
(section "Messages - Info Key", page 4.18 )
• Loading and storing complete instrument settings in the File menu
(section "Storing and Loading Instrument Data - File Key", page 4.19 )
The RF signal is configured in the RF function block:
• CW mode
(section "RF Signal - RF", page 4.25)
• Frequency and Level Sweep mode
(section "Sweep Mode", page4.44 )
The analog modulations are activated in the Mod function block:
• Amplitude Modulation
(section "Amplitude Modulation - AM", page 4.62)
• Frequency Modulation
(section "Frequency Modulation - FM", page 4.65)
• Phase Modulation
(section "Phase Modulation - PhiM", page 4.68 )
• Pulse Modulation
(section "Pulse Modulation", page 4.72 )
The internal LF generators, the LF frequency sweep and the pulse generator is configured in the Mod
Gen function block:
• LF Frequency Sweep
(section "LF Frequency Sweep Menu", page 4.76)
• LF Output
(section "LF Output Menu",page 4.81)
