Comparator function of list sweep: The comparator function enables setting one pair of
lower and upper limits for each measurement point.


You can select from: Judge with the first sweep parameter/Judge with the second
parameter/Not used for each pair of limits.

Time stamp function: In the sequential mode, it is possible to record the measurement
starting time at each measurement point by defining the time when FW detects a trigger
as 0 and obtain it later with the SCPI command.

Comparator function

Bin sort: The primary parameter can be sorted into 9 BINs, OUT_OF_BINS, AUX_BIN,
and LOW_C_REJECT. The secondary parameter can be sorted into HIGH, IN, and LOW.
The sequential mode and tolerance mode can be selected as the sorting mode.

Limit setup: Absolute value, deviation value, and % deviation value can be used for setup.

BIN count: Countable from 0 to 999999.

Measurement assistance functions

Data buffer function: Up to 201 measurement results can be read out in a batch.

Save/Recall function:
• Up to 10 setup conditions can be written to/read from the built-in non-volatile memory.
• Up to 10 setup conditions can be written to/read from the USB memory.
• Auto recall function can be performed when the setting conditions are written to
Register 10 of the USB memory.

Key lock function: The front panel keys can be locked.

GPIB: 24-pin D-Sub (Type D-24), female; complies with IEEE488.1, 2 and SCPI.

USB host port: Universal serial bus jack, type-A (4 contact positions, contact 1 is on
your left), female (for connection to USB memory only).

USB interface port: Universal serial bus jack, type mini-B (4 contact positions); complies
with USBTMC-USB488 and USB 2.0; female; for connection to the external controller.


USBTMC: Abbreviation for USB Test & Measurement Class

LAN: 10/100 BaseT Ethernet, 8 pins (two speed options)

LXI Compliance: Class C (only applies to units with firmware revision A.02.00 or later)

Note

The following USB memory can be used.
Complies with USB 1.1; mass storage class,
FAT16/FAT32 format; maximum consumption
current is below 500 mA.

Recommended USB memory: 512 MB USB
Flash memory (Agilent PN 1819-0195).

Use the recommended USB memory device
exclusively for the E4980A, otherwise,
previously saved data may be cleared. If you
use a USB memory other than the recommend-
ed device, data may not be saved or recalled
normally.

Agilent Technologies will NOT be responsible
for data loss in the USB memory caused by
using the E4980A.
