There are two modes of operation, Normal and Programming/Setup. Both modes of operation utilize the front panel LED Display. In the Normal Mode, there are two states, Monitoring Mode and No-Monitoring. In the Monitoring Mode the LED display indicates the RMS reading of the signal present at the output of the selected channel. The Non-Monitoring Mode turns off the LED display for lower noise applications and to minimize power consumption. In the Programming Mode, the unit is ready for manual programming or editing of existing channel setups. The unit will automatically return to the Normal Mode of operation after 20 seconds of inactivity of the front panel or after pressing the “Select Function” push-button while the “Monitoring State” function LED is flashing.
The rear panel contains (on a per-channel basis) a BNC output connector, a 9-pin “D” input connector, the RS-232 connector, and the input power connector.Three Model 136 units may be configured in a 19-inch rack mount adapter. The standard unit is powered by 90-264 VAC,50/60 Hz.The -1 option is powered by 9 to 18 VDC, making it ideal for portable use or for automobile test applications.
