Sampling
CW Mode & Modulation Mode 2.5 to 5.0 MHz, Asynchronous
Analog Bandwidth
CW Mode ≥3 kHz
Modulation Mode >10 MHz
Time Gated Measurements
Gate Time 5 µs to 100 ms
Trigger Delay 0 to 100 ms
Holdoff Time 0 to 100 ms
External Trigger Polarity Positive or negative leading edge
Delay & Range Accuracy ±1.5 µs or ±100 ppm of the set time, whichever is greater
Settability 1 µs steps or selective by cursoring to specific digits
Trigger Signal Standard TTL levels
Gate Polarity Specifies the external signal TTL high or low level as true for
defining the gated time.
