How to solve pass thorugh command ignored issue when setting a signal analyser MXA N9020A

I am trying to set up the signal analyser using a simple python script. I am able to set the center and frequency and span frequency but when i am trying to turn the average on and set it to exponential mode, it gives me a pass through command ignored. The instrument is connected successfully using LAN.

import string

import pyvisa # PyVISA package for connecting to the instrument

 

pyvisa.log_to_screen()

 

# Make connection to instrument

# Open a VISA resource manager pointing to the installation folder for the Keysight Visa libraries.

rm = pyvisa.ResourceManager()

 

# Device addr

addr_MXA = 'TCPIP0::A-N9020A-00060::inst0::INSTR'

addr_VSA = 'TCPIP0::CASCODA500::hislip1::INSTR'

SA_device = rm.open_resource(addr_VSA)

 

# Preset and wait for operation to complete

SA_device.write('*rst')

SA_device.query('*opc?')

 

# Resume the sweeping

SA_device.write('init:cont ON')

SA_device.write('init:res')

 

# Measurement variables for the MeasSetup

freq = '2.44GHz'

freq_span = '5MHz'

count = 10

avermode = 'EXP'

search_len = '832us'

 

SA_device.write('sens:freq:cent {}'.format(freq))

SA_device.write('sens:freq:span {}'.format(freq_span))

# Average

SA_device.write('sens:aver ON')

SA_device.write('sens:mon:aver:tcon {}'.format(avermode))

SA_device.write('sens:aver:count {}'.format(count))
