201 to 702: | ESG Family Signal Generators |
Uncalibrated signal; Quadrature Skew Not Calibrated
A calibration is required to use the quadrature skew feature. The quadrature skew may be functional, but is not guaranteed to meet specifications until the I/Q impairment adjustment is performed. Refer to the calibration guide.
520Sampler unlocked
One of the signal generator’s samplers is unlocked or one of the sampler circuits are malfunctioning. The instrument may require service.
521Yig unlocked
The Yig oscillator phase lock loop is unlocked. Problem may be due to a bad calibration. If not, then the instrument may require service.
522Demodulator Unleveled; Input amplitude overrange.
The signal level is too high. Adjust the signal level for the VSA input.
Demodulator Unleveled; Input amplitude underrange.
The signal level is too low. Adjust the signal level for the VSA input.
600RPP has tripped.
The reverse power protection circuit has been triggered. Repeated tripping of this circuit can cause damage to the instrument.
**** CAUTION ****
REVERSE POWER PROTECTION (RPP) TRIPPED
Repeated RPP tripping may damage the instrument!
Damage can occur if an external signal was applied at the RF Output or ESD is detected at RF Output.
Damage will not occur if a poor RF output port match exists when the power level is set beyond the specified range.
601Power search failed.
While executing power search, the level meter circuit failed to return a meaningful value. This event indicates that the power is in a range that the leveling loop cannot properly level. The power will be set to the last properly leveled power.
604DSP FW download failed.
An external bus download of a digital signal processor (DSP) program failed.
