Requirements for Verification
The M9202A is verified by using it to trigger on and visualize a signal from a Function Generator. The trigger
must be stable and the signal frequency and amplitude must correspond to that set on the generator.
Required Hardware
To verify that the module works requires an external signal source which will be sent to both the input and the
trigger. Almost any sine wave or function generator capable of generating a signal with a Peak-Peak Amplitude in
the range 0.1-2 V at a frequency in the range 100-500 MHz can be used. The rest of this description will assume
that an Agilent N5181A MXG RF Analog Signal Generator is available for this purpose.

1x BNC - BNC cable
50 Ω Coaxial BNC(m) - BNC(m) cable (min 20 cm)
1x Agilent 11667L Splitter
DC to 2 GHz Power Splitter with BNC connector
1x BNC - SMA cable
50 Ω Coaxial BNC(m) to SMA(m) cable (100 cm)

Operational Verification Procedure
Do not exceed the maximum power level to the INPUT connector (0.5 W).
1. Launch the soft front panel (SFP). The calibration must successfully end as noted above.
2. Configure the RF Generator to produce a Sine signal with a Frequency of 100 MHz, an Amplitude of 560
mV pp (+8.0 dBm), and an Offset of 0 V.
3. Connect the RF GENERATOR output to the Splitter with the Adaptor and the BNC-BNC cable. Using the
BNC-SMA cable, connect one Splitter output to INPUT 1. Use the BNC-MMCX cable to connect the other
Splitter output to the TRG1 input. Turn on the RF GENERATOR output.
4. Configure the SFP for the Oscilloscope Mode.
5. Select the 'Connect data points' option from the 'View' menu.
6. Configure the Input for:
l
Trigger Level 1 –
0.0 V
l
Input Voltage Offset –
0.0
l
Trigger Delay –
0.0
l
Trigger Source –
M9202A EXT1
l
Timebase –

7. Select the NORMAL Acquisition mode and the Waveform Display should be as shown below.
8. Verify that:
o
the waveform shown is stable from one acquisition to the next,
o
the period of the signal is 2 divisions
o
the pk-pk amplitude is 8 ± 0.6 divisions
