General Specifications
Inputs/Outputs
Current requirement U2041/42/43/44/53/63XA: Approximately < 500 mA
U2049 and L2051/52/53/61/62/63XA: 3W, 802.3af or 802.3at Type 1 standard
Trigger input Input has TTL compatible logic levels and uses a SMB connector
Trigger output Output provides TTL compatible logic levels and uses a SMB connector
Remote programming
Interface U2041/42/43/44/53/63XA: USB 2.0 interface USB-TMC compliance
U2049 and L2051/52/53/61/62/63XA: 10/100 Mbps RJ-45 Power Over Ethernet port, transfers
data and power on one single cable, 802.3af or 802.3 at Type 1 compliant
Command language SCPI standard interface commands, IVI-COM, IVI-C drivers
Maximum measurement speed (Applicable for USB & LAN socket connectivity)
Free run trigger measurement 25,000 readings per second
1
External trigger time-gated measurement 20,000 readings per second
2
Average mode real time measurement 50,000 readings per second
3
1. Tested under normal mode and fast mode, with buffer mode trigger count of 100, output in binary format, unit in watt, auto-zeroing, auto-calibration, and
step detect disabled.
2. Tested under normal mode and fast mode, with buffer mode trigger count of 100, pulsed signal with PRF of 20 kHz, and pulse width at 15 µs.
3. Tested under average only mode and fast mode, with buffer mode trigger count of 200, aperture duration of 20 µs, data format set to real, external trigger
or immediate trigger setting. For LAN socket connectivity, network traffic might affect the measurement speed intermediately. Direct LAN connection to
computer via PoE injector would provide the fastest measurement speed.
Mechanical Characteristic
Mechanical characteristics such as center conductor protrusion and pin depth are not performance specifications. They are, however,
important supplemental characteristics related to electrical performance. At no time should the pin depth of the connector be
protruding.
