Physical measurements
Table 23 lists frequency and level measurement specifications when running DS1 appli-
cations.
E1 specifications
When testing E1 circuits, either BNC or RJ48 connectors can be used. 5882 supports
E1 only on RJ48.
Clock source
(Timing) – Internal reference clock with accuracy ±1.5 ppm, ±1 ppm
per year aging
– Recovered from RX1
– External from BITS, SETS, or CLOCK
Frequency offset ±100 ppm, in 1 ppm steps
Pulse shape Terminated with 100
Ω
resistive load and 0 dB LBO
selected, the interface meets ITU-T Recommendation
G.703 (11/01) and ANSI T1.102-1993

Parameter Specification
Table 23 DS1 frequency and level measurement specifications
Parameter Specification
Level V p-p Range: 8.0 V to 0.06 V
Accuracy: ± 0.04 V ± 10%
Resolution: 0.01 V
Frequency Range: 1.544 MHz ±250 ppm
Accuracy: ± 1.5 ppm, ± 1 ppm per year aging
Resolution: 1 Hz or 1 ppm
Level dBdsx
1
1. The designation dBdsx is a level measurement in dB relative to dsx level, which is 6 V peak-peak. A signal with a
peak-peak level of 6V corresponds to 0 dBdsx.
Range: +2.5 dBdsx to -37 dBdsx
Resolution: 0.1 dB
Level dBm
2
2. Available only when unframed all ones (AIS) signal is detected.
Range: +19.0 dBm to -10.5 dBm
Resolution: 0.1 dB
NOTE:
For the 5800 v1, 5811P and 5822P, the E1 and DS1 interfaces should not be
connected at the same time. Multiple connections can influence the integrity of
the signal under test. After running your test, disconnect from one interface
before connecting to the other interface.
