Ds0 Freq/Ds0 Level - Fluke 635 User Manual

DS1 Level (dBDSX)
When the DS1 level result is selected (using the RESULTS keys), the test set
displays the level of the DS1 signal in dBDSX. A DS1 signal is transmitted at
a 0 dBDSX level. The reading, therefore, indicates the loss (in dB) from the
point of transmission to the point of measurement.

DS0 Frequency
DS0 frequency is a measurement of the analog frequency for the DS0 that is
currently being monitored. For example, a test tone that is being received (in
the selected DS0) will be measured and the received frequency will be
displayed. The test set demodulates the digitally-encoded signal on the selected
channel and presents it through the speaker (and the headset jack). If the DS0
frequency result is selected (using the RESULTS keys), the frequency of the
analog signal present on the channel is displayed in Hz. (This result display is
only available if a channel has been selected for monitoring.)
DS0 Level
DS0 level is a measurement of the analog signal level for the DS0 that is
currently being monitored. For example, a test tone that is being received will
be measured and the received level (or amplitude) will be displayed. The test
set demodulates the digitally-encoded signal on the selected channel and drops
the channel to the speaker (and the headset jack). If the DS0 level result is
selected (using the RESULTS keys), the level of the signal is displayed in
dBm. If you know the level at which the tone signal is inserted, the insertion
loss of the channel may be determined. (This result display is only available if
a channel has been selected for monitoring.)
