Differential Outputs

(Agilent E1445A

Commander)

These examples show you how to use the amplifier’s differential (small signal) outputs. Note the following when using the outputs:

the differential (small signal) outputs are designed for high-frequency and low-power source applications.

with no attenuation, the maximum input voltage (sum of Input1 and Input2) must not exceed 2 Vpp (Figure 2-1).

In the first example, the E1446A is a servant to the E1445A. In the second example, the E1446A is a servant to the E1405 Command Module.

Rather than amplify the input signal, this program attenuates the signal supplied by the E1445A to obtain an output amplitude of 10 mVpp. The output can be taken at either the ’Diff +’ or ’Diff -’ (inverted) output.

The steps of this program are:

1.Reset the E1445A AFG and E1446A amplifier.

*RST

2.Set the AFG frequency, function, and (minimum) amplitude.

[SOURce:]FREQuency[1][:CW:FIXed] <frequency>

[SOURce:]FUNCtion[:SHAPe] <shape>

[SOURce:]VOLTage[:LEVel][:IMMediate][:AMPLitude] <amplitude>

3.Couple the AFG output load value to the output impedance value.

OUTPut[1]:LOAD:AUTO <mode>

OUTPut[1]:IMPedance <impedance>

4.Set the amplifier input impedance to match the AFG output load.

INPut[1]:IMPedance <impedance>

5.Set the amplifier input attenuation.

INPut[1]:ATTenuation <attenuation>
