NPLC caching
NPLC caching speeds up operation by caching A/D reference and zero values for up to the ten most
recent measurement aperture settings. Whenever the integration rate is changed using the SPEED
key, or a user setup is recalled, the NPLC cache is checked. If the integration rate is already stored in
the cache, the stored reference and zero values are recalled and used. If the integration rate is not
already stored in the cache, a reference and zero value will be acquired and stored in the cache when
the next measurement is made. If there are already ten NPLC values stored, the oldest one will be
overwritten by the newest one. When autozero is off, NPLC values stored in the cache will be used
regardless of age.

Basic source-measure procedure

Front-panel source-measure procedure
Use the following procedure to perform the basic source-measure operations of the 2606B using the
virtual front panel. The following procedure assumes that the 2606B is already connected to the
device under test (DUT), as explained in
Hazardous voltages may be present on all output and guard terminals. To prevent electrical
shock that could cause injury or death, never make or break connections to the 2606B while
the instrument is powered on. Turn off the equipment from the front panel or disconnect the
main power cord from the rear of the 2606B before handling cables. Putting the equipment
into standby does not guarantee that the outputs are powered off if a hardware or software
fault occurs.
Step 1: Select and set the source level
To select the source and edit the source value:
1. Press the SRC key as needed to select the voltage source or current source, as indicated by the
units in the source field on the display. The flashing digit (cursor) indicates which value is
presently selected for editing.
2. Move the cursor to the digit to change, then press the navigation wheel
mode.
3. Use the RANGE keys to select a range that will accommodate the value you want to set. See
Range
range.
4. Enter the source value.
5. Press the ENTER key or the navigation wheel
Step 2: Set the compliance limit
To edit the compliance limit value:
1. Select the CONFIG key.
2. Select the LIMIT key.
3. Select CURRENT or VOLTAGE.
4. Select the ENTER key or the navigation wheel .
5. Move the cursor to the digit to change, then press the navigation wheel
mode, as indicated by the EDIT indicator.
6. Enter the limit value, then press the ENTER key or the navigation wheel
