Options

Hardware Options

Model: MG3700A-001

Name: Rubidium Reference Oscillator

This option provides a 10 MHz reference signal VCO.

The frequency stability is better than the standard VCO.

Frequency: 10 MHz

Aging rate: ±1 × 10

–10

/month

Temperature stability: ±1 × 10

–9

(0° to +50°C)

Model: MG3700A-002

Name: Mechanical Attenuator

This option changes the standard electronic attenuator to a

mechanical attenuator, improving the maximum permissible

output level and distortion characteristics.

Settable range: –140 to +19 dBm

Accuracy range (CW): –140 to +10 dBm

Model: MG3700A-011

Name: Upper Frequency 6 GHz

This option extends the upper frequency to 6 GHz from 3 GHz.

Model: MG3700A-021

Name: ARB Memory Upgrade 512 Msamples

This option extends the memory capacity of the ARB unit to

256 Msamples/channel × 2 from 128 Msamples/channel × 2.

Model: MG3700A-031

Name: High-speed BER Test function

This option upgrades the standard built-in BER

measurement functions as follows:

• Increases the data rate to a range of 100 bps to 120 Mbps

• Added SyncLoss count function

• Added discontinuous PN data measurement function

• Added user pattern measurement function

adjustment

Can perform continuous measurement of high

error rates by changing measurement conditions to

match error rates.

Auto Resync = OFF is required for manufacturing

inspection of some communications systems

requiring reception sensitivity with BER=1%, and

for R&D applications that evaluate reception

sensitivity limits.

function

—

√

This can be used for continuous measurement

even when synchronization loss occurs.

Measurement of

discontinuous PN

data

—

√

When the size of continuous data such ISDB-T

PN23 exceeds the MG3700A memory capacity,

measurement can be performed by reducing the

memory requirements using discontinuous PN data.

User pattern

measurement

—

√

This can be used for measuring xed patterns such

as those specied by WiMAX.

∗:

The measurement count of the standard BER measurement function (version 2.02 or earlier)

could be set as Time and Number of bits. The High-speed BER Test Function option does

not have the Time setting, and can set Number of bits and Number of error bits.
