Modulation frequency: 10 µHz to 0.2 Hz (sine wave)

Amplitude: 0 to 57,600 UIp-p (30 UIp-p steps)

Line wander generation

Accuracy: ±Q% ±160 UIp-p

Auto wander measurement

Wander sweep measurement

Reference wander generation is valid when MU150005A/150006A/150007A Option 03 is mounted.

Off: Able to set non-modulated status

Reference wander

TDEV mask:

generation

The 37 types of TDEV masks that are regulated by ITU-T, ETSI, ANSI, and Bellcore standards are available as default.

It is possible to add the wander modulation to the user specified TDEV mask.

Transient: It is possible to change the A (1 – e

–63.7t

) phase by the timing of the start.

Signal off: It is possible to disconnect the standard signal.

Wander measurement is valid when MU150005A/150006A/150007A Option 02 is mounted. Conforms to ITU-T O.172

Reference input: 2.048M (HDB3, clock), 1.544M (AMI/B8ZS, clock), 64k + 8 kHz, 5 MHz, 10 MHz
