(2) Sequence 5 timing is prog rammable under IEEE bus con trol
(3) As reading is displayed, LED corresponding to appropriate
display and function mode will illuminate.
(4) The IEEE-Bus option. due to a change in the RF step attenuator,
restricts the maximum RF output to
.,.1 1
dBm .
NON-CONTROLLABLE FUNCTIONS
Since control and monitor functions of the inter-
face are implemented to obtain remote measure-
ment capability , certain front panel controls are
not implemented in the interface due to their
local operator orientation . A list of these oper-
ator oriented controls are as follows:
Power On/ 011
Power Mode Indicators
Display Focus
Display Intensity
Dispersion/ Sweep
Scope/ DVM Vertical Vernier
Scope Trigger Level
