ELECTRO-METRICS EM-2115 2.0 OPERATING INSTRUCTIONS
(EM2115S2-4)
c.
Connect the power cord between the A14J2 Power Connector and the AC power
source.
d.
Turn on the EM-2115 by pushing in the front panel Power Switch. The LED indi-
cators should be lighted when the unit is on. Allow a minimum warm-up time of
30 minutes.
NOTE:
Whenever the EM-2115 is powered up, the UNCAL INDICA-
TOR will be lighted indicating that the unit is not calibrated.
The calibration sequence can only be initiated by pushing the
front panel CAL Switch or by a Cal Command issue by the
computer in REMOTE.
2.3.2 Pre-Operational Calibration
2.3.2.1 Cw Calibration
The EM-2115 employs an internal impulse generator to amplitude-calibrate the receiver.
The calibration function is activated when the front panel CAL Switch is pushed or by a remote
command signal via the rear panel IEEE-488 (GPIB) Interface Bus connector.
Whenever a calibration sequence is initiated, the UNCAL Indicator (incorporated in the
CAL Switch) is lighted for the duration of the sequence--approximately two seconds. If calibra-
tion of the receiver cannot be accomplished, the UNCAL Indicator will remain lighted, alerting
the operator to this fact. If the receiver will not calibrate, contact the
Electro-Metrics Customer
Service Department (518) 762-2600
or the nearest
Electro-Metrics representative
for any as-
sistance required.
