Notes about Using USB Devices

• Connect the USB memory device to the USB port for peripherals (type A) directly, not through a USB hub.

• Use portable USB storage media that are compatible with USB Mass Storage Class version 1.1.

• You cannot use protected USB storage devices (such as those that contain encrypted content).

• Only connect compatible USB keyboards, mouse devices, or memory devices to the USB ports for

peripherals.

• Do not connect and disconnect multiple USB devices repetitiv

ely. Provide a 10-second interval between

removal and connection.

• Do not connect or remove USB devices from the time when th

e WT1800 is turned on until key operation

becomes available (approximately 20 to 30 seconds).

• The WT1800 can handle up to two USB memory devices.

Saving Setup Data (Save Setup)

You can save the WT1800 setup data to the specified storage medium. The date, time, and communication

setup parameters are not saved.

The extension is .SET.

For information about the file save conditions, see “File Save Conditions.”

Saving Waveform Display Data (Save Wave)

You can save the waveform data that the WT1800 has measured to a file in ASCII format (.csv). The waveform

displayed on the screen is saved.

For information about the file save conditions, see “File Save Conditions.”

Click here.

The waveform display data that the WT1800 saves is not the sampled waveform data that is acquired at the

WT1800 sample rate (of approximately 2 MS/s). The WT1800 performs P-P compression on the sampled

waveform data, to produce 1602 points of waveform display data that are used to display the waveform on

the screen.

Saving Numeric Data (Save Numeric)

You can save the numeric data that the WT1800 has measured to a file in ASCII format (.csv).

For information about the file save conditions, see “File Save Conditions.”

Click here.

When you save numeric data and a point has no numeric data, NAN, OL, OF, ERROR, or a blank space will

be saved instead. The places that contain blank spaces are in measurement functions such as the ones for

the 0th (DC) and 1st harmonic orders of ΦU and ΦI, where the screen display is also blank.
