STEP GAIN/ATTN FAIL

Indicates the step gain has failed. (H)

Stop at marker not available with negative detection

Indicates that the marker counter cannot be used when negative peak detection is selected. To use the marker counter, turn off negative peak detection with DETECTOR PK SP NG (U)

TABLE FULL

Indicates the upper or lower table of limit lines contains the maximum number of entries allowed. Additional entries to the table are ignored. (U)

TG SIGNAL NOT FOUND

Indicates the tracking generator output signal cannot be found. Check that the tracking generator output (RF OUT 75 f2) is connected to the cable TV analyzer input connector with an appropriate cable. (U)

TG UNLVL

This message can indicate the following: that the source power is set higher or lower than the cable TV analyzer can provide, that the frequency span extends beyond the speciEed frequency range of the tracking generator, or that the calibration data for the tracking generator is incorrect. See “Stimulus-Response Measurements” in Chapter 5 of this guide for more information. (U)

Too many signal with valid N dB points

Indicates the N dB PTS function has located two or more signals that have amplitudes within the specified dB from the signal peak. If this happens, you should decrease the span of the cable TV analyzer so that only the signal that you want to measure is displayed. (U)
