10.9.2 Dynamic Level Accuracy for the R3765BG/67BG
This section describes the detail test procedure of the dynamic level accuracy. This section
applies only to the R3765BG/67BG.
10.9.2.1 Specifications
Reference level : -19 dBm
(-24 dBm for OPT 10, -28 dBm for OPT 10 + OPT 12, -23 dBm for OPT 12)
0 dB to -10 dB : ±0.20 dB (300kHz to 3.8GHz)
0 dB to -10 dB : ±0.40 dB (3.8GHz to 8GHz)
-10 dB to -50 dB : ±0.05 dB
-50 dB to -60 dB : ±0.10 dB
10.9.2.2 Instruments Required

Recommended model: HP8496B
• RF cable (SMA(m)/SMA(m) 50Ω) quantity=2
Recommended model: A01253-060
• Adopter (N(m)/SMA(f)) quantity=2
Recommended model: HRM-554S
• 3-dB attenuator (SMA(f)/SMA(m)) quantity=2
Recommended model: AT-103
• 50Ω to 75Ω conversion adapter (75Ω N(m)/50Ω N(f)) × 2: 11852B (For OPT 12)
10.9.2.3 Procedure
(1) Connect two 3-dB attenuators and step attenuator using two RF cables between TEST
PORT 1 and TEST PORT 2 shown in Figure 10-31.
Figure 10-31 Connections for TEST PORT 1 Measurement
for Dynamic Level Accuracy
* Connect the 50Ω to 75Ω
conversion adapter to
TESTPORT 1 and 2 for
OPT 12.
Note that the 3 dB fixed
attenuator is not required.
