Sage Instruments 930i Communications Test Set
The delay is measured and displayed for each frequency in the sweep. If the 930i is in PRINTER remote
mode the 930i will automatically print the delays. (Refer to
Section 5-3,
OPTION MENU
#:3, Remote
Control,
or
Section 6, Remote Control Operation
.
)
8. Press K4 under
STOP?
to interrupt the sweep, without leaving the
SEND
mode.

3400Hz -16dBm <-SEND STOP?

When the sweep completes or is interrupted, the 930i will revert to sending the reference frequency and
K4 will again be labeled
SWEEP
. The sweep can be repeated or the frequency of the signal can be
manually set to examine the delay at frequencies of interest.
9. Press K3 under
<-SEND
to examine the level and frequency of the returned carrier. The received
level and frequency is displayed and the label above K3 changes to:
<-RECV
.
10. Press K3 under
<-RECV
to toggle between viewing the outgoing signal and the returned carrier
at any time. An example display of the returned reference carrier while sweeping from the Send
unit is shown below:
0µS
1804Hz -16dBm <-RECV STOP?
K1
K2
K3
K4
The carrier level should be within the 0 dBm to -40 dBm range and steady for the test to be valid.
When the measurements are complete, the operator at the send end can alert the operator at the repeat
end to sweep the return carrier. This will allow a forward reference measurement to be made of the return
path delay. The Send unit transmits the fixed reference signal toward the Repeat unit, (Slave unit) at
the far-end.
11. Press K3 on the SEND unit to display the received frequency for the delay.
5-17.3 Repeat
To place the 930i at the far end of the circuit in Repeat mode:
1. Press K3 under
REPEAT
from the main
SELECT
display. A high pitched tone sounds and the
display reads:
