This is performance that will be met by 80% of
instruments with 80% confidence, for ambient
temperatures in the range of 18 °C to 28 °C,

include the effects of the uncertainties of external
calibration references and aging over the course of
the published calibration interval. These values are
determined from qualification testing and are not
warranted or tested in the performance verification.

This is performance that will be met by 95% of

put Timing

All I/Q ou tput signals are synchronous to clock EXT_IQ_CLK. The clock
operates at either 50 MHz or 200 MHz, depending on the selected real-time span
of the analyz

er. (See Table 59 on page 63.)

Data is valid when the EXT_IQ_DAV signal is asserted high; data is invalid when
EXT_IQ_DAV

is low. The EXT _IQ _D AV duty cycle varies with the real-time
SPAN, as shown in the following table. At spans where the duty cycle is less than
100%, the EXT_IQ_DAV signal is high for one clock cycle, then low for one
or more clock cycles.

When any of these conditions are active, the EXT_IQ_DAV signal will be held in
its inactive state. The EXT_IQ_CLK signal will remain active and operate at the
frequency consistent with the SPAN value selected for the analyzer.

The EXT_IQ_DAV signal will remain inactive for the duration of any alignment
or control change. Once the alignment or control change has been completed, the
EXT_IQ_DAV signal becomes active again. While the EXT_IQ_DAV signal is
inactive, the data from the digital I/Q outputs are not valid and should be ignored.

values to a very small percentage at the narrowest SPAN values. (See Table 58.)
At a SPAN of 100 Hz, the duty c ycle will be 0.00038%; here, the EXT_IQ_DAV
signal is active (high) for 20 ns, and then inactive (low) for ≈5.28 ms.

The length of tim e that the EXT_IQ_DAV signal is inactive can be used to
determine if the analyzer is performing an alignment or a control change. If the
EXT_IQ_DAV signal is inactive for longer than 10 ms, then the SPECMON
analyzer digital I/Q output data stream has been interrupted.

External equipment used to detect the occurrence of a data interruption can
monitor the state of the EXT_IQ_DAV signal. If the EXT_IQ_DAV signal is
inactive
duration of the data interruption can be determined by measuring the time between
successive EXT_IQ_DAV pulses.

a. Center Freq

b. Span (Span key): 10 kHz.

c. Select Run > Run Single.

d. Set the Marker Frequency to 1010 MHz.

NOTE. The intent of the Phase Noise test is to measure the phase noise level of

the instrument. The phase noise specification does not cover residual spurs. If
the spe
is visible above the noise level, the phase noise specification applies not to
the spur but to the noise level on either side of the spur. Please refer to the
Spurious Response specifications. (See Table 15.) Also, refer to the Spurious
Response section of this procedure to determine whether or not a residual spur
is within the specification. (See page 118, Spurious Response.)

For example, if Carrier Power = 4.7 dBm and M1 = –146.1 dBm/Hz,

Then M1-Carrier Power = –150.8 dBc/Hz.

1. Connect the RF generator, power splitter, power meter, and spectrum analyzer,
as shown in the following figure.

The power splitter outputs should connect directly to the SPECMONB RF
Input and to the Power Sensor, without using cables.

2. To record the test readings, you can make a printout of the following table.
(See Table 64.)

3. Reset the spectrum analyzer to factory defaults: Setup > Preset (Main).

7. Set both th e RF s

ignal generator output frequency and the spectrum analyzer
Center Frequency to the first frequency in the RF Flatness table that follows.
This is the reference frequency. (See Table 62.)

8. Select the Markers Peak key to set the Reference Marker (MR) to the carrier
peak.

9. Adjust the RF signal generator output level for a marker reading of –20
±0.5dBm.

10. Record the Power Meter reading and the SPECMONB marker reading in the
following table.

11. Set both the RF Generator output frequency and the SPECMONB center
frequency to the next frequency in the table.

12. Press the Markers Peak key to set the Reference Marker (MR) to the carrier
peak.

13. Calculate the ΔPower Meter number: subtract the Power meter reading at
100 MHz from the Power Meter reading at this frequency.

14. Calculate the ΔRTSA number: subtract the RTSA reading at 100 MHz from
the RTSA reading at this frequency.

15. Calculate the RF Flatness Error:

RF Flatness Error = ΔRTSA at this freq – ΔPower Meter at this freq

Readings are in dBm, error is in dB.

16. Repeat items 11 through 15 for each of the center frequencies shown in the
RF Flatness table up to the maximum bandwidth of the device-under-test.
