Anritsu MS2665C - 7.4 Performance test

7-11
7.4 Performance test
7.4.1 Option 04 Hi-speed time domain sweep
(1) Required equipment :
6769B Swept frequency synthesizer (Anritsu)
(2) Specifications :
Setting range : 12.5 usec, 25 usec, 50 usec, 100 usec to 900 usec (One most significant digit settable), 1.0 ms to 19 ms
(Two upper significant digits settable)
Accuracy : ±1%
Marker level resolution : 0.1 dB (LOG scale), 0.2% (Linear scale, relative to reference level)
(3) Setup :
Connect the spectrum analyzer’s RF Input to 6769B RF OUTPUT.
(4) Measurement :
1) Initialize the spectrum analyzer and the 6769B.
2) After “All Cal”, set the spectrum analyzer to :
Center frequency, 100 MHz
Span, 0 Hz
Sweep time, 12.5 usec
RBW, 1 MHz
VBW, 1 MHz
Set the 6769B to :
FREQUENCY, 100 MHz
RF LEVEL, -16 dBm
MODULATION, AM (Internal) 90%
MODULATION FREQ, 1.6 MHz
3) On the spectrum analyzer, press “→Ref” key, set the scale to Linear, and then press “Single” key.
4) After sweeping, move the spectrum analyzer’s marker onto left most peak of the sine wave using the knob.
5) On the spectrum analyzer, set the marker function to delta marker mode, and then move the marker onto the 18th
peak from the left most peak.
6) Read the difference of the delta marker, which correspond to 90% of time span.
