Proceed as follows to connect the NGMO to the AC line and turn on: Before plugging in the power cable, make sure that the power switch is off (the “POWER“...
  • Page 28 Operation Power Supply NGMO Example 1 line 1: "AS" means that currently the settings for channel A are displayed. • If you turn the output on by pressing the "OUTP. on/off" key the display changes to "AM" indicating that this is now a measured value taken from the output terminals of the selected power supply.
  • Page 29 Power Supply NGMO Operation manual setting keys are disabled except the local key and those to change the display mode. This makes it easier for software deve- lopers to verify that their software is running correctly. When a lock command has been received from the IEEE interface the NGMO2 enters the lock state.

  • Page 30: Menu

    Operation Power Supply NGMO 4.2.3 Menu There are two ways of entering numerical settings. The first way is to use the variation knob (16, Fig. 3-1) and the arrow keys (14, 15, Fig. 3-1). The second is to use the keys with the extra blue labels. 4.2.3.1 How to Enter a Numerical Value Using the Variation Knob?
  • Page 31 Power Supply NGMO Operation NOTE: If you are in the Menu mode and you have selected a function that accepts numerical entries, the direct numerical input mode can be activated by pressing the SHIFT key without first pres- sing the ENTER key. However, it is also possible to first select the variation knob entry mode by pressing the ENTER key and then entering the direct numerical entry mode by pressing the SHIFT key.
  • Page 32 Operation Power Supply NGMO 4.2.3.4 Menu Items The menu includes a selection of items from A01 or B01 to A38 or B38: (The indicated channel A or B depends on which channel is selected.) A/B01: Current range [AUTO] 5A .5A 5mA This function selects the range for static current measure- ment (see main screen) and also selects the current range for signal analysis.
  • Page 33 Power Supply NGMO Operation A/B06: Sample Channel [Current DVM] This menu items lets you select the source for the NGMO2 analysis functions. When “current” is selected the analysis functions use the internal current measure circuits for analysis (ranges 5A or .5A). In “DVM” mode the external DVM inputs are used for analysis.
  • Page 34 Operation Power Supply NGMO A/B11: Trigger Source [int] ext The trigger source function lets you select either an internal trigger source (see A/B07 to A/B09) or use an external trigger signal to start an analysis measurement. The external trigger signal can be applied on the rear panel.
  • Page 35 Power Supply NGMO Operation A/B16: Sample Interval (0.01-1000 ms) The sample interval is the time interval between two consecutive samples used for measurement or signal analysis. Both the “Sample length” and the “Sample Interval” makes the total measuring time for one sample cycle.
  • Page 36 Operation Power Supply NGMO A/B20: READ xxx Value (Result) The “READ xxx Value” menu item (xxx = AVER PEAK MIN HIGH LOW RMS) (see also A/B19) displays the result for the selected analysis function. If there is no result available (because there is no data that can be analyzed) only a line is displayed.

  • Page 38 Operation Power Supply NGMO A/B31: Serial interface [on] off When set to ON, a RS232 connection to the NGMO2 can be used as a remote interface. This setting is independent of the setting made with menu item 29 (Recall setting when power on).
  • Page 39 Power Supply NGMO Operation A/B35: Serial count of stopbits [1] 2 This menu item is used to select “Serial count of stopbits” for data transmission. When set to 1, only one stopbit is transmitted before the start of the next data byte. When set to 2, two stopbits are transmitted before the next data byte - this means synchronisation is better but there are fewer transfers per second.

  • Page 45: Measurements

    Operation Power Supply NGMO Measurements The NGMO2 provides three multiplexed measure channels on each supply channel (A/B) for the measurement of output VOLTAGE and CURRENT as well as for the additional DVM input. The VOLTAGE channel is used only for static measure functions (readback), CURRENT and DVM channels are used for static and dynamic measu- re functions.

The sample interval can be set between 10 µs and 1 s in 10 µs steps. At sample intervals greater than 10 µs the NGMO2 measure system samples internally in 10 µs intervals and averages the taken samples to build values in the selected time intervals.
