Trigger
• Channel Functions: A, B, A/B, B/A, A−B, B−A, and relative.
• Storage Registers: 10 instrument states can be saved via Save/Recall
menu.
• Predefined setups: For common wireless standards (GSM900, EDGE,
NADC, iDEN, Bluetooth, IS- 95 CDMA, WCDMA
and cdma2000),predefined setups are provided.
• Sources: Internal, External TTL, GPIB, and RS232/422.
• Time Resolution: 50 ns.
• Delay Range: ±1.0 s.
• Delay Resolution: 50 ns for delays <±50 ms otherwise 200 ns.
• Hold- off: Range: 1
μ
s to 400 ms
Resolution: 1% of selected value (minimum of
100ns).
• Internal Trigger: Range:
−
20 to +20 dBm
• Level Accuracy: ±0.5 dB
• Resolution: 0.1 dB
• Latency: 500 ns ± 100 ns
Latency is defined as the delay between the
applied RF crossing the trigger level and the
power meter switching into the triggered state.
• External Trigger
Range:
High >2.0 V, Low <0.8 V; BNC connector; rising or
falling edge triggered; input impedance >1 kΩ
• Trigger Out: Output provides TTL compatible levels (High >2.4
V, Low <0.4 V) and uses a BNC connector.
