Amplitude Area - Agilent Technologies X Series User Manual

This annunciator appears when...
BBG DAC A DAC overflow is occurring, adjust the runtime scaling adjust until the BBG DAC annunciator turns off.
Another annunciator, UNLOCK, appears in the same position and has priority over the BBG DAC annunciator
(see UNLOCK, below).
The internal channel correction is enabled.
CHANCORR
The ALC detector heater is not up to temperature. To meet ALC specifications the heater must be at
DETHTR
temperature.
The digital bus is in use.
DIGBUS
Custom Arb waveform generator is on.
DIGMOD
An error message is placed in the error queue. This annunciator does not turn off until you either view all of
ERR
the error messages or clear the error queue (see
An external frequency reference is applied.
EXTREF
Frequency modulation is on. If you turn phase modulation on, the ΦM annunciator replaces FM.
FM
I/Q vector modulation is on.
I/Q
The signal generator is in listener mode and is receiving information or commands over the GPIB, USB, or
L
VXI–11/Sockets (LAN) interface.
M–TONE Multitone waveform generator is on.
A frequency multiplier is set (see
MULT
An output offset is set (see
OFFS
Phase noise interference is on.
PN
Pulse modulation is on.
PULSE
R The signal generator is remotely controlled over the GPIB, USB, or VXI–11/Sockets (LAN) interface. When the
signal generator is in remote mode, the keypad is locked out. To unlock the keypad, press Local.
REF An output reference is set (see
The signal generator's RF Output is not enabled.
RF OFF
S The signal generator has generated a service request (SRQ) over the GPIB, USB, or VXI–11/Sockets (LAN)
interface.
The signal generator is currently sweeping in list or step mode.
SWEEP
The signal generator is in manual sweep mode.
SWMAN
T The signal generator is in talker mode and is transmitting information over the GPIB, USB, or VXI–11/Sockets
(LAN) interface.
Two–Tone waveform generator is on.
T–TONE
The signal generator is unable to maintain the correct output level. This is not necessarily an indication of
UNLEVEL
instrument failure; unleveled conditions can occur during normal operation. Another annunciator, ALC OFF,
appears in the same position when the ALC circuit is disabled (see ALC OFF, above).
Any of the phase locked loops cannot maintain phase lock. To determine which loop is unlocked, examine the
UNLOCK
error messages (see
The current modulation mode is waiting on the Arb trigger.
WATRG
WINIT The signal generator is waiting for you to initiate a single sweep.
