measurement range.
Verify the spectrum of the DUT’s output signal.
Decrease the IF Gain value, or increase the sweep start value when possible.
• The DUT’s output signal is being modulated in frequency.
Stop the frequency modulation.
• A large harmonics component is included in the DUT’s output signal.
Insert a low-pass filter between the DUT’s output terminal and the E5052B RF IN
connector to eliminate the harmonics component.
211 System PLL frequency range over
This error occurs when the internal PLL circuit becomes unlocked while the measurement
is in progress. This error may occur when the frequency of the input signal is out of range.
212 System PLL Input overflow
This error occurs when the internal PLL circuit becomes unlocked while the measurement
is in progress. This error may occur when the level of the input signal is too large.
214 System FLL unlocked
This error occurs when FLL version of “210 system PLL unlocked”. When the capture
range in PN measurement in Normal, it’s 210 and When Wide, 214.
215 System FLL frequency range over
This error occurs when FLL version of “211 system PLL frequency range over”. When the
capture range in PN measurement in Normal, it’s 211 and When Wide, 215.
-310 System error
One of the errors designated as “system errors” in this instrument has occurred.
T
110 Target freq out of range
This error indicates the 2nd, 3rd, or nth order harmonics is not within the E5052B
measurement range. At this time, the previous measurement conditions still remain (any of
sweep parameters are not changed).
-223 Too much data
The block-, expression-, or character-string-type program data that have been received
conform with the standard but exceed the amount that can be processed under the
conditions of the memory or conditions specific to memory-related devices. In this
instrument, this error occurs when the number of characters exceeds 254 in a
character-string parameter.
-211 Trigger ignored
This instrument receives and detects a trigger command (“TRIG”) or an external trigger
signal, but it is ignored due to the timing conditions (the instrument is not in the wait-for-
trigger state, for example). Change the setup so that a trigger command or an external
trigger signal can be sent after the instrument has entered the wait-for-trigger state.
